• Clear all filters (✕ Clear) — rightmost toolbar button; resets search text, group filter, and badge filter (ALL) in one click

Canvas Snapshot (v0.1.2)

• One-click capture — click the camera button in ComfyUI's top bar to snapshot the current workflow canvas
• Auto-save as thumbnail — the snapshot is saved directly to the workflow data folder as a PNG thumbnail
• Embedded workflow metadata — workflow JSON is embedded in the PNG (tEXt chunk), compatible with ComfyUI's drag-and-drop import
• Auto-import — the captured workflow is automatically imported and appears in the Workflow tab

GenerateUI Tab (v0.3.5)

• 5-tab layout — Input / Model / Settings / Feeder / Batch tabs; Input, Model, and Settings each include a Raw JSON column on the right for instant preview and direct editing
• Save button — located at the right end of the subtab row; opens a filename dialog (default: current workflow name) and saves the current workflow as a .json file to the Workflow tab via the import API
• Input tab — Prompt and Image inner tabs (drag-and-drop upload); Prompt tab shows Positive Prompt and Negative Prompt textareas, plus an Embeddings selector at the bottom (Filter + Select + Weight input + Paste button); Paste inserts (embedding:Name:weight) at the cursor position of the last focused textarea (defaults to Positive when neither is focused); Raw JSON (540px) in the right column
  • Revert button (v0.3.70) — a ↺ button next to each Apply button reverts the textarea to the node's currently applied value (the reverse of Apply)
  • Emphasis weight editing (v0.3.70) — select text (or just place the cursor on a word/parenthesis block) and press Ctrl+↑/↓ to adjust (text:weight) by ±0.05, A1111/native-ComfyUI style; parentheses are removed automatically when the weight returns to 1.0
• Model tab — Checkpoint, VAE, LoRA, ControlNet, Diffusion Model (UNETLoader / UnetLoaderGGUF / LoaderGGUF), Text Encoder (CLIPLoader / DualCLIPLoader / ClipLoaderGGUF / DualClipLoaderGGUF — single clip: type + device; dual clip: two clip selectors + type + device), Hypernetwork (with Strength field) selectors with filter; Raw JSON on the right
• Settings tab — KSampler and Latent Image side by side at 50% width each; Raw JSON on the right
• Always-visible Raw JSON — edit the API-format JSON directly from any tab with syntax highlighting; Apply button reloads the workflow; built-in search bar (always shown) finds all matches as you type with count display (3/12); navigate with ↑/↓ buttons or Enter / Shift+Enter; Escape or ✕ clears; current match highlighted in orange, other matches in yellow
• One-click generation — queue prompts to ComfyUI without leaving the studio
• Seed control — randomize, lock, or manually set seeds; seed input and mode selector stacked vertically for readability
• Style selector — checkbox and dropdown next to the Reset Workflow button; enable to apply a Fooocus-style JSON to positive and negative prompts at generation time; style files (*.json) are loaded from user/default/Workflow-Studio/style/; the style's {prompt} placeholder is replaced with the original prompt text, or the style is appended if no placeholder exists; negative_prompt is appended to the existing negative prompt; styles are applied to a per-generation copy and do not modify the loaded workflow
• Batch type selector — check one of the column header checkboxes in the Batch Queue pane (Checkpoint / Lora / Prompt / Workflow / Sampler / Scheduler / Style) to activate that batch type; only one type can be active at a time; the Batch panel below Generate shows the active type, progress, and Pause/Resume/Stop controls
• Batch tab (v0.3.18) — dedicated 3-pane layout for assembling the batch queue:
  • Left pane — 4 tabs: Checkpoints (file-tree; Filter / All / None), Sampler (KSampler sampler list), Scheduler (KSampler scheduler list), Style (flat list of all styles from Workflow-Studio/style/; All / None buttons)
  • Center pane — group-based selection with inner tabs (Checkpoint | Lora | Prompt | Workflow); Checkpoint/Lora groups come from the Models tab, Prompt groups from the Prompt tab, Workflow groups from the Workflow tab — check a group to add all its members, expand ▶ to select individually
  • Right pane (Batch Queue) — 7 columns: Checkpoint / Lora / Prompt / Workflow / Sampler / Scheduler / Style; each column header has an enable checkbox (radio behavior: only one at a time); count shown per column; Style batch applies each selected style sequentially to a workflow copy
  • Lora batch prompt sync (v0.3.69) — for each selected LoRA, its syntax (<lora:name:strength_model:strength_clip>) and CivitAI trained words are automatically appended to the Positive prompt (rebuilt from the original prompt each time, not accumulated), then restored to the pre-batch state when the batch completes or is stopped; if a selected LoRA is not yet recognized by ComfyUI's model list, a warning toast suggests a Refresh or restart
• UI-to-API conversion — automatic conversion supporting subgraphs (nested workflows), COMBO types, and display-only node exclusion; improved analysis covers SDXL multi-hop CONDITIONING chains, CLIPTextEncodeSDXL, SDXLPromptStyler, KSamplerAdvanced, and more
• Eagle integration — auto-save generated images to Eagle with metadata

Feeder subtab (v0.3.5 / v0.3.42)

Two independent modes selectable via [Image Loop] / [Gallery] toggle buttons at the top of the left pane (persisted in localStorage).

Image Loop mode — requires the comfyui-image-feeder custom node.

• ImageFeeder node control — select the target node from a dropdown auto-populated from the loaded workflow; edit all node parameters (Directory, Sort Mode, Index, Start/End Index, Batch Size, Seed, Use Selection) and Apply to the workflow
• Image library — 3-pane layout: folder tree (left) browsing user/default/image-loop-data/, image grid with checkbox selection (center), preview panel with resolution and file size (right)
• Selection management — check individual images; All / None buttons for the current folder; selected files are reflected in selected_files on Apply
• Presets — save the current directory + selection as a named preset; load or delete presets (server-side persistence via image-feeder-presets.json)
• Continuous Run loop — Run / Stop buttons below the presets; After gen mode controls index behavior after each generation:
  • Loop — advance index and wrap back to 0 when all images are exhausted (runs indefinitely)
  • Increment — advance index and auto-stop when all images are consumed
  • Fixed — always use the same index
• Index sync — after each generation the node returns next_index via WebSocket (image_loop_node_sync); the Index field updates automatically
• Seed — Run loop uses the right-pane seed setting (Random / Fixed / Increment / Decrement); the node's own Seed field only affects random sort order

Gallery mode (v0.3.42) — no external plugin required; uses the built-in WFS_GalleryFeeder custom node.

• WFS_GalleryFeeder node — reads images directly from a Gallery group and outputs them one at a time; inputs: group_name, index, sort_mode (filename_asc / filename_desc / random), seed
• Node & group selector — pick the WFS_GalleryFeeder node from the loaded workflow and choose which Gallery group to feed images from; __Feeder__ group is auto-created on first open
• Image grid — center pane shows all images in the selected group; click any image to update the Index to that position
• After Gen modes — Loop (wrap at end and continue indefinitely), Increment (stop automatically when last image is reached), Fixed (always use the same index)
• Run / Stop controls — left pane Run / Stop buttons manage the generation loop; After Gen combo (loop / increment / fixed), ▶ Run, and ■ Stop widgets are also available directly on the WFS_GalleryFeeder node in the ComfyUI canvas (gallery_feeder_extension.js)

Changelog

v0.3.70

• Workflow AI summary — Ollama 404 fix — the summarize button in the workflow detail modal now uses the Ollama URL/model saved in Settings → AI Assistant Settings (previously it silently fell back to a hardcoded default model tag that didn't match locally installed models, causing a 404)
• Image Edit — New button auto-adds Layer 1 — creating a blank canvas via the New button now automatically adds an empty "Layer 1", matching the existing image-load behavior
• Image Edit — mask overlay shown only for the active mask layer — previously every visible mask layer's overlay was rendered regardless of selection; now only the currently active mask layer shows its overlay, other mask layers stay hidden until selected
• GenerateUI — Revert button for Positive/Negative Prompt — a ↺ button next to each Apply button reverts the textarea to the node's currently applied value
• GenerateUI — Ctrl+↑/↓ prompt emphasis weight editing — A1111 / native ComfyUI CLIP Text Encode style: select text (or just place the cursor on a word/parenthesis block) and press Ctrl+↑/↓ to adjust (text:weight) by ±0.05; parentheses are removed automatically when the weight returns to 1.0

v0.3.69

• Gallery — Send CC button — new toolbar button, shown only when the Gallery tab is embedded as an iframe inside ComfyUI Comic Creator (a separate custom node); sends the selected image directly into Comic Creator's currently selected panel/overlay via its existing insertImageFromUrl(url) helper (no changes required on the Comic Creator side)
• Lora batch — validation fix — fixed a Prompt outputs failed validation error where LoRA files that actually existed were rejected by the standard LoraLoader node; the root cause was a path-separator mismatch (ComfyUI on Windows returns \-separated enum values while WFS tracked LoRAs internally with /); a shared resolveLoraName() helper now converts to ComfyUI's actual notation before applying, used consistently by Lora Single apply, Stack apply, the Models tab GenUI Model button, and Lora batch generation
• Lora batch — pre-flight check — before running a batch on a standard LoraLoader workflow, selected LoRAs are checked against ComfyUI's current model list; if any are not yet recognized, a warning toast suggests a Refresh or ComfyUI restart (skipped for Lora Manager–based workflows, which have no enum constraint)
• Lora batch — automatic prompt sync — for each LoRA applied during a batch, its syntax (<lora:name:strength_model:strength_clip>) and CivitAI trained words are automatically appended to the Positive prompt, rebuilt from the original prompt each time (not accumulated); the prompt is automatically restored to its pre-batch state when the batch completes, is stopped, or errors
• Models tab — Close button in detail modal — added a Close button at the right end of the Save / GenUI PP·NP / Delete button row in the model detail modal (all sub-tabs), reducing mouse travel to the top-right ✕ during repeated batch edits
• Help — new help entry (helpGen19) added in EN / JA / ZH describing the Lora batch prompt sync, restore, and pre-flight check behavior

v0.3.68

• Image Edit — MASK EDITOR ONE section always visible — the ABR brush section in the Draw tool's (MASK EDITOR ONE (COLOR)) and Mask Paint mode's (MASK EDITOR ONE) Properties pane is now always shown instead of being hidden when no brushes are imported; the header text turns green when at least one ABR brush is available and gray when none are imported yet; the Select button is disabled until a brush exists
• Help — MASK EDITOR ONE status — updated helpImageEdit5 (Draw tool) and helpImageEditMask4 (Mask Paint mode) in EN / JA / ZH to describe the always-visible section and its color-coded availability state

v0.3.67

• GenerateUI — Alt+Click Apply & Generate — Alt+Click any Apply button to apply the parameter and immediately queue a generation in one step; applies to Positive Prompt Apply (Input tab), all model Apply buttons (Model tab: Checkpoint / VAE / Diffusion Model / ControlNet / Hypernetwork), and KSampler Apply (Settings tab); only triggers generation when the target node exists in the loaded workflow (no action on missing nodes); each Apply button shows a tooltip Apply (Alt+Click: Apply & Generate) on hover
• Help — Alt+Click Apply & Generate — new help entry (helpGen18) added in EN / JA / ZH

v0.3.66

• Image Edit — Mask Tool: 5 new sub-tools — Paint / Color / Alpha / Text / Vector / Shape / SAM3 (7 sub-tools total); Color, Alpha, Text, Vector, and Shape work without Mask Editor One
  • Color — click the canvas to flood-select pixels similar in color to the clicked point; Properties pane: Mode (Add / Subtract), Tolerance (0–255), Feather % (0–100)
  • Alpha — extract the active layer's alpha channel as a mask; Properties pane: Threshold, Invert checkbox, Extract Alpha button
  • Text — click to open a stamp overlay; enter text, set Font / Size / Bold / Italic / Align / Mode (Add / Erase), confirm with Stamp or Ctrl+Enter; multi-line text supported
  • Vector — click to add Catmull-Rom spline control points; Enter (or click the first point) closes and fills the polygon; Backspace removes the last point; Esc resets; Mode (Add / Erase)
  • Shape — drag to draw a rectangle or ellipse; hold Shift for a perfect square/circle; blue dashed outline preview while dragging; Properties pane: Mode (Add / Erase), Shape (Rect / Ellipse)
• Help — Support page — added ComfyUI Image Feeder and Mask Editor One GitHub repository links to the Support card

v0.3.65

• Image Edit — Mask Editor One integration fixes — store_image API field mismatch (image_b64 → bg_image_b64) corrected so BiRefNet and SAM3 no longer report "no image available"; server.py updated to accept both field names for backward compatibility
• Image Edit — top bar icon persistence — WFS / Snapshot / Node Sets SVG icons in the ComfyUI action bar disappeared when the Properties Panel was opened (Vue re-render reset custom innerHTML to <i>); fixed with a MutationObserver that re-applies SVG icons whenever a reset is detected
• Image Edit — Mask Tool: ABR brush library (requires Mask Editor One) — Select button in the Properties pane opens a folder-tree + thumbnail-grid brush picker; stamp brushes are loaded from Mask Editor One's /mask_editor/brushes/ folder; ✕ clears back to the default circle brush
• Image Edit — Mask Tool: ABR brush controls — when an image brush is active, Hardness is disabled and new controls appear in the Properties pane: Spacing (stamp interval 5–100%), Angle (fixed rotation 0–359°), Sz Jitter (random size reduction per stamp 0–100%), Rot. Jitter (random angle per stamp on/off); size jitter clamped to minimum 1 px to prevent zero-dimension canvas errors
• Image Edit — Mask brush cursor — brush size circle is now hidden outside the canvas; only shown when the pointer is within the canvas bounds (window-level mousemove no longer shows the cursor overlay outside)

v0.3.64

• Image Edit — Mask layer Add/Subtract — A/S toggle button on each mask layer row; Add (green, default) composites the mask normally; Subtract (red) cuts the mask area from the layer below; multiple mask layers are composited back-to-front matching Mask Editor One's CanvasCompositor logic
• Image Edit — BiRefNet BG Remove (requires Mask Editor One + birefnet.safetensors in ComfyUI/models/background_removal/) — BiRefNet model now fully functional via Mask Editor One's Python backend; grayscale mask returned as RGBA PNG and applied as a new layer or in-place per the New Layer toggle
• Image Edit — SAM3 segmentation (requires Mask Editor One) — new SAM3 sub-tool in the Mask tool options bar; enter a text prompt, set Max candidates (3/6/9/12), click Segment; candidate mask thumbnails shown in the Properties pane; click to select (multi-select), Apply Selected (N) applies all chosen masks with Add or Erase mode; new mask layer auto-created if active layer is not a mask

v0.3.63

• Nodes tab — multi-select — Ctrl+click to toggle individual nodes, Shift+click for range selection; bulk action bar appears with add to group / remove from group / create & add group / bulk favorite / unfavorite; works in both Card and Table view modes
• All tabs — search clear (✕) — inline ✕ overlay button inside each search box (Workflow / Nodes / Models / Gallery); shown only when text is entered, click to clear and re-filter immediately
• All tabs — clear all filters button — new ✕ Clear button at the rightmost end of each tab's toolbar; resets all active filters (search, group, tag, folder, favorites, badge) in one click; Gallery sort order is preserved

v0.3.62

• Gallery tab — Send GenUI Image button — new toolbar button (next to Image Edit); uploads the selected image to ComfyUI and sets it as the input for the first LoadImage node in the GenerateUI tab; automatically switches to GenerateUI → Input → Image; comfyEditor.applyImageToSlot(file, slotIndex) added to comfyui-editor.js for reusable image-slot injection
• Bug fix: tagger_settings.json missing from data export — tagger_settings.json was absent from _DATA_FILES in settings_routes.py; Tagger model directory and threshold settings were silently excluded from Settings → Data Management export/import; fixed by adding the file to the export list
• Help — Send GenUI Image — new help card (helpGallery17) added in EN/JA/ZH; registered in helpIdMap
• Screenshots — Tagger and Image Edit tabs — docs/12_Tagger.png and docs/13_ImageEdit.png added to the README screenshots section

v0.3.61

• Image Edit — Draw / Mask brush cursor — cursor replaced with a size-accurate circle overlay matching the current brush size; the circle scales correctly with canvas zoom so the visible area matches exactly what will be painted
• Image Edit — Draw / Mask out-of-canvas strokes — strokes can now start from the canvas margin area (outside the image boundary) and continue past the edge without interruption; window-level mousemove / mouseup tracking keeps the stroke alive when the pointer leaves the canvas element
• G'MIC — argument order fix — corrected gmic_qt.exe launch arguments to -o <output> <input> (the only order G'MIC-Qt Standalone accepts); the previous order caused the GUI to exit immediately without opening
• G'MIC — settings path placeholder — replaced the hard-coded user-specific default path with a generic C:\path\to\gmic_qt.exe placeholder; settings load without a pre-filled path for new users
• G'MIC — security: path traversal fix — POST /api/wfm/gmic/result now validates that result_path is inside the gmic_temp directory before reading the file; requests for paths outside that directory are rejected with 403
• Help — G'MIC Filter section — added two new help cards (G'MIC Filter usage and G'MIC-Qt Installation) with full i18n support (English / Japanese / Chinese)

v0.3.60

• Image Edit — Filter tool (G'MIC-Qt integration) — the previously inactive ★ Filter tool now launches G'MIC-Qt GUI with the active layer image; select a filter and click OK, then close the "G'MIC-Qt filter output" window to apply the result back as the active layer; polling-based job system with progress display, Cancel button, and Undo support; requires G'MIC-Qt Standalone (gmic_qt.exe) configured in Settings
• Settings — G'MIC-Qt Executable Path — new collapsible section in Settings for entering and saving the path to gmic_qt.exe

v0.3.59

• Image Edit — Mask Tool — new Mask tool (🎭) in the Image Edit sidebar; click M in the Layers header to add a mask layer (Mask tool activates automatically); clicking a mask layer in the layer list also switches to the Mask tool; Tool Options bar: Paint button, Invert checkbox (inverts overlay preview), Overlay color picker (default red), Blur slider (0–50 px) for overlay edge softening; Properties pane (left of the Layers panel, shown when Mask tool is active): Size (1–200 px), Hardness (0–100%), Mode — Add / Erase toggle buttons (active mode highlighted in blue)
• Image Edit — Clipping mask (✂ button) — each mask layer row shows a ✂ toggle; when enabled (blue), the mask clips the layer directly below it so only the painted area is visible; clipping is applied to PNG save / Save to Gallery / Send to ComfyUI exports
• Image Edit — Draw & Mask paint bugfix — Draw and Mask tools now paint directly onto layer.canvas; all other layers remain fully visible during brush strokes (previously the composite view was replaced by the active layer only while painting)
• Image Edit — Layer panel width — increased from 190 px to 220 px to accommodate the additional ✂ button on mask layer rows
• Help — Mask Tool section — added Mask Tool card with full i18n support (English / Japanese / Chinese); updated Tools list, layer type icon list, and Layer panel "M button" description

v0.3.58

• GenerateUI Model tab — Diffusion Model GGUF support — LoaderGGUF and LoaderGGUFAdvanced nodes are now recognized alongside UNETLoader / UnetLoaderGGUF; the correct input key (gguf_name vs unet_name) is selected automatically on Apply; the Models tab "GenUI Model" button also applies correctly to LoaderGGUF workflows
• GenerateUI Model tab — Text Encoder expanded (CLIPLoader / DualCLIPLoader / GGUF variants) — the Text Encoder section now renders a node-type-aware UI: single CLIP (CLIPLoader / ClipLoaderGGUF) shows one clip selector + type dropdown + device (GGUF only); Dual CLIP (DualCLIPLoader / DualClipLoaderGGUF) shows two clip selectors (clip_name1 / clip_name2) + type dropdown + device (GGUF only); type options are fetched dynamically from /object_info; filter applies to the first selector only

v0.3.57

• Image Edit — Blur tool — new Blur tool (≈) in the Image Edit sidebar; Whole Blur: Gaussian blur to the entire active layer with intensity slider (1–50 px); Whole Mosaic: pixelation mosaic with block-size slider (5–100 px); Rect Blur / Rect Mosaic: toggle to enter rect-draw mode then drag to select a region — blur or mosaic is applied on mouse release; Rect Blur and Rect Mosaic are mutually exclusive; all operations support Undo (Ctrl+Z)
• Image Edit — BG Remove tool — new BG Remove tool (⬚); Lightweight (@imgly): background removal running entirely in the browser via CDN (~40 MB model cached after first load); BiRefNet: stub wired to a future Python backend endpoint (coming soon); New Layer checkbox (default on) adds the result as a new layer above the original — uncheck to replace the active layer in-place; supports Undo
• Image Edit — sidebar icons — removed ie-tool-placeholder dimming from Blur and BG Remove buttons; both now display at full brightness matching other active tools
• Help — Blur / BG Remove sections — added two new help cards (Blur Tool and BG Remove Tool) with full i18n support (English / Japanese / Chinese); Tools list updated with Blur and BG Remove overview items

v0.3.56

• GenerateUI — Style selector — new checkbox and dropdown next to the Reset Workflow button; when enabled, a Fooocus-style JSON style is applied to positive and negative prompts at generation time; style files (*.json) are read from user/default/Workflow-Studio/style/; multiple files are merged into a single list sorted by filename; the style's {prompt} placeholder is replaced with the original prompt text, otherwise the style text is appended; negative_prompt is appended to the existing negative prompt; styles are applied to a per-generation workflow copy and never modify the loaded workflow
• Batch tab — Style batch — new Style tab in the Batch left pane lists all styles loaded from the style directory (flat list with All / None buttons); select any combination, enable the Style column in Batch Queue, then Generate to run each selected style sequentially; Batch Queue expanded from 6 to 7 columns (Style added as the rightmost column)

v0.3.55

• Group feature — fix data loss on Windows (backslash/slash mismatch) — on Windows, ComfyUI returns model paths with backslashes (sub\model.safetensors) while the backend normalized to forward slashes; this caused all subdir group members to be flagged as missing and deleted on save; fixed by normalizing both stored and scanned paths to forward slashes in get_model_groups and save_model_groups
• Group feature — network drive protection — if no model directories are accessible (e.g. external drive disconnected), the group cleanup step is now skipped entirely to prevent wiping all group memberships
• Group feature — scan cache — _scan_model_names now caches results for 30 seconds to eliminate redundant full directory scans on startup (caused high CPU load / crash on large model sets)
• Group feature — RESERVED_GROUPS protection — bulkRemoveFromGroup and renderPmGroups now prevent Batch/Stack reserved group keys from being deleted even when all members are removed
• Group feature — stale groupFilter reset — after deleting a group, state.groupFilter is automatically cleared if it pointed to the now-deleted group (previously showed 0 models)
• Group feature — toggleGroupEnable partial failure — only models listed in data.ok are updated client-side, preventing state divergence when some enable/disable calls fail
• GenerateUI batch groups — restore Batch/Stack visibility — reverts an incorrect filter that hid Batch and Stack groups from the batch group selection UI; these groups are now selectable for batch execution as intended
• GenerateUI LoRA groups — path normalization — backslash-to-slash normalization added after fetching LoRA groups from the API, matching the Checkpoint fix
• Batch complete toast — i18n — replaced hardcoded English toast with t("batchComplete", ...) supporting all 3 languages
• Prompt tab migration — fix negText loss — migrateLocalStoragePresets now correctly passes negText when calling apiCreatePreset, preventing negative prompts from being silently dropped during localStorage→API migration
• Help tab — Image Edit section i18n — the Image Edit help page was hardcoded in English with no language switching support; all 6 sections (30 items + 7 headings) now have i18n IDs wired to English / Japanese / Chinese translations

v0.3.54

• Image Edit — Shape tool (S) — new Shape tool added to the Image Edit toolbar; draw Rect, Ellipse, Line, and FreeLine shapes by dragging; each committed shape becomes an independent draw layer that can be undone in a single step; Tool Options: shape type selector, Rounded toggle (Rect/Ellipse only), Fill color + None toggle (hidden for Line/FreeLine), Stroke color + width (Stroke None hidden for Line/FreeLine where stroke is always active), Opacity slider, Undo button; blue dashed outline previews the shape during drag; keyboard shortcut S activates the tool
• Models tab — fix B/S overlay buttons not highlighting — the Batch (B) and Stack (S) card overlay buttons failed to turn yellow after clicking because e.currentTarget is nulled by the browser after an async event handler yields at await; fixed by capturing const btn = e.currentTarget before the await in both handlers

v0.3.53

• Image Edit Tab — new layer-based image editing tab with Select / Draw / Text tools, multi-layer compositing, canvas zoom & pan, and Undo/Redo; text layers are sized to exact bounding-box dimensions and regenerated at display resolution on resize to prevent blurring; double-click a text layer to re-edit its content; Gallery tab gains an "Image Edit" toolbar button to send the selected image directly to the editor
• Image Edit — Layer lock — lock icon (🔒/🔓) on each layer row; locked layers display an orange bounding box and ignore all Select-tool transforms; Layer 1 is auto-locked when the first image is loaded to prevent accidental moves
• Image Edit — Save to Gallery — "Save to Gallery" button (next to Save PNG) saves the composite image to the Gallery root folder; filename defaults to wfs-image-YYYYMMDDHHmmss; backed by new POST /wfm/gallery/image/save API endpoint
• Help tab — Image Edit page — new dedicated help page covering tools, layer panel, text quality, export options, and keyboard shortcuts

v0.3.52

• GenerateUI Model tab — fix LoRA selection reset when switching subtabs — applying a LoRA via "GenUI Model" button and then switching to another subTab (Prompt/Image/Settings) and back to Model caused the LoRA selector, syntax display, and trigger words to revert to the original workflow values; fixed by reading currentVal directly from currentWorkflow instead of the stale currentAnalysis, and by saving/restoring the Single tab's syntax and trigger words across re-renders

v0.3.51

• Models tab — Embedding type: GenUI PP / GenUI NP buttons — Embedding models now show two buttons ("GenUI PP" and "GenUI NP") in the side panel nav, detail side panel, and detail modal (replacing the single "GenUI Model" button); clicking either appends (embedding:Name:1.0) to the Positive or Negative prompt of the loaded workflow
• GenerateUI Prompt tab — Embeddings selector — new section at the bottom of the Prompt tab: Filter input, model select dropdown, Weight input (default 1.0), and Paste button; Paste inserts (embedding:Stem:weight) at the cursor position of the last focused textarea (Positive or Negative); focus state is tracked on click/keyup/blur so the button works even after clicking away
• GenerateUI Model tab — Hypernetwork support — Hypernetwork section added with model selector (filter) and Strength field; applies to HypernetworkLoader nodes in the workflow; GenUI Model button in Models tab also triggers Hypernetwork apply
• Models tab — fix Embedding and Hypernetwork models not shown — _fetchModelList now handles the ComfyUI V3 node format (options key) in addition to V1/V2 formats; fetchEmbeddings switched from the /embeddings ComfyUI endpoint to the WFS backend API (/api/wfm/models/files?type=embedding) to avoid SPA URL routing conflicts
• Models tab — GenUI Model button in side panel nav — "GenUI Model" button added to the tab navigation bar (Info / Group / CivitAI) of the side panel; appears for supported model types (Checkpoint, LoRA, VAE, etc.) and hides for unsupported types; Embedding type shows PP/NP nav buttons instead

v0.3.50

• Gallery tab — fix prompt search causing ComfyUI hang under large folders — the v0.3.49 on-demand metadata read ran synchronously on the aiohttp event loop, blocking ComfyUI when folders contained many uncached images; fixed by: (1) removing on-demand reads from list_images(); (2) wrapping list_images() in asyncio.to_thread() to keep the event loop free; (3) adding a background indexer (start_background_index) that automatically indexes uncached images after a folder is loaded — processes 10 images per batch with a 50 ms sleep between batches; cancellable on folder switch

v0.3.49

• GenerateUI tab — A1111-style SPA-side wildcard expansion — when prompt text in non-ImpactWildcard nodes (e.g. CLIPTextEncode) contains __name__ syntax, the SPA expands it at generation time by randomly picking a line from the matching file in the WFS wildcard folder; nested wildcards are re-expanded up to 5 passes; unresolved wildcards are passed through unchanged; ImpactWildcardEncode/Processor nodes are skipped (handled server-side by Impact Pack); works in both single and batch generation
• Gallery tab — fix Export button missing label — the bulk action bar's Export button had no text label because the textContent assignment was missing from updateUITexts(); fixed by adding the galleryBulkExport i18n key assignment alongside the existing Move/Delete entries
• Gallery tab — fix prompt search not matching images with no cached index — prompt_cache was only built when an image was opened in the detail panel; A1111 images (or any images never opened) were invisible to prompt search; now when search is active and prompt_cache is empty, the image file is read on-demand and the cache is populated and persisted for future searches

v0.3.48

• Gallery tab — single image download — hover over a detail-panel preview image to reveal a download overlay (⬇ icon); click to download the original file with its original filename preserved
• Gallery tab — bulk export to ZIP — multiple selected images can be exported as a ZIP archive via the "Export" button in the bulk action bar; filename: gallery_export_<timestamp>.zip; backend: POST /wfm/gallery/images/export-zip with path-traversal protection

v0.3.47

• Models tab — fix stale group state after file move — when models were moved to a subdirectory via "Move To...", state.modelGroups in the JS client was not updated to reflect the new model paths; the group filter view would lose the moved models immediately after the operation. Now the client-side group membership is updated in sync with the server-side rename (mirrors the existing Python move_models logic). Generate tab Batch groups are unaffected as they always fetch fresh from the server.

v0.3.46

• Prompt tab AI Assistant — LM Studio support — switched from Python proxy (/api/wfm/ollama/*) to direct browser-to-backend API calls (same pattern as the AI TOOL tab); supports Ollama (/api/chat) and LM Studio (/v1/chat/completions); image attachments are automatically converted to the correct format per backend
• Settings tab — AI Assistant Settings (Prompt Tab) — renamed from "Ollama Settings"; added backend selector (Ollama / LM Studio), URL input with per-backend placeholder, model select with Refresh, and Test button; settings saved to localStorage wfm_prompt_ai_settings (independent of AI TOOL tab settings)
• Auto-refresh on backend change — if the backend is switched in Settings tab while Prompt tab is already open, sendMessage() now detects the mismatch and automatically re-fetches the model list before sending; model status shows the active backend name ([ollama] / [lmstudio])
• Help text updated (EN/JA/ZH) — Prompt tab, Settings tab, and Troubleshooting sections updated to reflect Ollama / LM Studio dual-backend support

v0.3.45

• Group auto-cleanup — Models tab — stale group entries (models that no longer exist on disk) are automatically removed when the Models tab is loaded or the model type is switched; models moved within the app via "Move To..." also update their group membership immediately
• Group auto-cleanup — Gallery tab (folder view) — metadata entries for missing files are cleaned up each time a folder is scanned (list_images), synchronized with the 60s TTL + folder-mtime cache
• Group auto-cleanup — Gallery tab (group image list) — list_images_in_group (used by the Feeder tab Gallery mode) now filters out non-existent paths and removes them from the group in a single write operation
• Gallery tab — Shift+click range selection — Shift+click selects all images between the last clicked item (anchor) and the current item; works in both thumbnail and table views; anchor is updated on Ctrl+click and regular click; resets on folder change, image reload, and Deselect All; help text updated (EN/JA/ZH)

v0.3.44

• Gallery tab — server-side thumbnail generation — GET /wfm/gallery/image/thumb?path=...&w=256 endpoint generates 256px JPEG thumbnails via Pillow and caches them to data/thumb_cache/ keyed by md5(path:mtime:width); GIF served as-is to preserve animation; falls back to the original file if Pillow is unavailable; thumbnail view and table view both switched from /image/serve to /image/thumb
• Gallery tab — infinite-scroll paging — thumbnail view renders 50 images initially; an IntersectionObserver sentinel (rootMargin 300px) appends the next page on scroll; sentinel is disconnected and removed when all images are rendered; paging resets on every renderImages() call (folder change, filter, sort)
• Gallery tab — bulk API endpoints — POST /wfm/gallery/bulk/favorite and POST /wfm/gallery/bulk/group handle favorite set and group add/remove for any number of images in a single request; replaced N-parallel individual fetches in bulkSetFavorite() and bulkAddToGroup()
• Gallery tab — image compare mode — Ctrl+click 2–4 images, then click "Compare" in the Bulk Bar to open a side-by-side lightbox; CSS grid adapts to the image count via --compare-cols custom property; close button is position:fixed at the top-right corner to avoid overflow:auto clipping
• Gallery tab — "Remove from Group" bulk button — new button in the Bulk Bar (right of "Add to Group"); uses the same group selector dropdown; calls POST /wfm/gallery/bulk/group with action:"remove"
• Gallery tab — bulk bar UI labels — dropdown placeholder "Add to Group..." → "Select Group"; "Add" button → "Add to Group"; "Delete" button → "Delete File" (distinguishes file deletion from group removal)
• Gallery tab — prompt search — text search now covers A1111 parameters text embedded in PNG/JPEG metadata; prompt text is extracted on first detail-panel open and stored as prompt_cache in metadata.json; subsequent list_images searches include prompt_cache without re-reading image files
• Help tab — Gallery mode i18n — Feeder subtab Gallery mode section (h4, description, 6 bullet points) now translated to Japanese and Chinese via i18n.js
• Help tab — font size ×1.5 — nav items, headings, body text, link cards, and support card text all scaled up in main.css
• Help tab — search box — live search input above the nav sidebar filters matching pages and auto-clicks the first result; placeholder text localized (EN/JA/ZH)

v0.3.43

• Send to Canvas — direct canvas load via window.opener — clicking "Send to Canvas" (Workflow tab) or "Copy & Send Canvas" (Gallery tab) now sends the workflow directly to the ComfyUI canvas without requiring a title drag; uses window.opener.wfmReceiveWorkflow() registered by node_sets_menu.js via app.handleFile(); both UI and API formats are supported; fallback to localStorage + title drag when window.opener is unavailable (e.g. opened from a bookmark), UI-format only
• Workflow Studio Library — API-format DnD enabled — API-format workflows in the W (Workflows) sub-tab are no longer grayed out; drag & drop and double-click now work for all formats via app.handleFile()

v0.3.42

• Feeder tab — Gallery mode — new [Image Loop] / [Gallery] toggle in the Feeder tab; Gallery mode drives a WFS_GalleryFeeder node without any external plugin: node selector, group select, sort mode / index / seed, After Gen (Loop / Increment / Fixed), Run / Stop; center pane shows the selected group's images — click any image to jump to that index; __Feeder__ group is auto-created on first open
• WFS_GalleryFeeder custom node — new ComfyUI node (Workflow Studio category) that reads images from a Gallery group and outputs one IMAGE at a time; inputs: group_name, index, sort_mode (filename_asc / filename_desc / random), seed; skips missing files; IS_CHANGED ensures re-execution on every queue
• WFS_GalleryFeeder — ComfyUI canvas controls — gallery_feeder_extension.js adds After Gen combo (loop / increment / fixed), ▶ Run button, and ■ Stop button as non-serialized widgets directly on the node in the ComfyUI canvas; manages per-node loop state with waitForExecution() Promise pattern; onRemoved hook auto-stops the loop on node deletion
• Gallery tab — thumbnail F button — cyan overlay button (top-left of each image card) toggles __Feeder__ group membership; active state is always visible in cyan, inactive shows only on hover; initial state derived from img.groups returned by list_images()
• Gallery tab — __Feeder__ reserved group — shown with 🔒 prefix in group dropdowns; rename and delete blocked server-side (403) and client-side (buttons disabled); FC toolbar button clears all group members without deleting the group
• Security: XSS fixes in gallery-tab.js — tag names, filenames, and server error messages now escaped via escapeHtml() before insertion into innerHTML (tag badge list, detail panel alt attributes, lightbox footer, folder tree errors, grid errors); util.js escapeHtml updated to also escape single quotes (' → ')
• Security: path validation in gallery_service.py — save_image_meta, toggle_favorite, add_to_group, remove_from_group now call _check_path_allowed() before any file operation; previously these four methods were missing the guard that other write methods already had
• Security: _init_allowed_root() in gallery_routes.py — _allowed_root is now initialized at module load from saved gallery_output_dir (falls back to ComfyUI default output dir); prevents list_folder_tree from overriding _allowed_root via a crafted ?root= request, and also fixes serve_image returning 404 in Feeder Gallery mode before the Gallery tab is opened
• Bug fix: WFS_GalleryFeeder seed validation error — seed max changed from 0x7FFFFFFF to 0xffffffffffffffff (matching KSampler); applySeedToWorkflow() was writing values exceeding the old max, causing value_bigger_than_max validation failures

v0.3.41

• Generate UI — ImpactWildcardEncode / ImpactWildcardProcessor prompt detection — fixed: wildcard text inputs from comfy-impact-pack nodes were not shown in the Prompt tab of Generate UI
  • CLIPTextEncodeEditPlus node (used as the text encoder in these workflows) now correctly propagates positive/negative roles upstream to ImpactWildcard nodes via BFS
  • CLIPTextEncodeEditPlus with an empty text_edit field is no longer added to prompt_nodes ahead of the upstream ImpactWildcard node, preventing a blank text area
  • widgets[0] is now always written to wildcard_text in the API conversion step, regardless of object_info widget-order differences between impact-pack versions
  • Static fallback mapping added for ImpactWildcardProcessor and ImpactWildcardEncode so detection works even when the ComfyUI server is offline

v0.3.40

• AI TOOL tab — Chat pane — new pane (between Translation and TOOLS) for multi-turn conversation with the LLM; full conversation history sent each turn for context; Enter to send, Shift+Enter for newline; Clear button resets history; Ollama uses /api/chat, LM Studio uses /v1/chat/completions
• AI TOOL tab — Wildcard generation — new "Create wildcards" task in the TOOLS pane dropdown; enter a category name and count, click Run to generate plain-text entries one per line (no markdown, no numbering); output can be pasted directly into wildcard .txt files
• Library A tab — Chat and Wildcards — both features added to the side panel's A tab: Chat as a new sub-tab (Translation → Chat → TOOLS → Settings), wildcard generation as a new option in the TOOLS sub-tab dropdown
• Help updated — AI TOOL tab help card updated to 6 items (Chat and Wildcards added); Library panel sidepanel-16 updated; EN/JA/ZH

v0.3.39

• Workflow tab — Send to Canvas button — replaced "Open in ComfyUI" (toolbar and detail modal) with "Send to Canvas"; stores the selected workflow in localStorage for title-drag to the canvas without opening a new browser tab
• Gallery tab — Copy & Send Canvas button — renamed "Copy Workflow" to "Copy & Send Canvas"; copies the embedded workflow JSON to the clipboard and simultaneously stores it for title-drag
• Workflow Studio Library — title drag — after "Send to Canvas" or "Copy & Send Canvas" is clicked, the "Workflow Studio Library" panel title turns blue with a green ● indicator; drag the title onto the ComfyUI canvas to load the workflow; title resets automatically after loading

v0.3.38

• Tagger tab — new tab for automatic image tagging; supports WD Tagger (ONNX), SwinV2, DeepDanbooru (.h5), and Ollama VLM; 3 sub-tabs: Single (drag & drop / upload, 5 output targets), Batch (folder processing with real-time progress), DB (searchable SQLite database with CSV export)
• Tagger single — GenUI:P button — new button (left of "Send to Prompt") that appends generated tags to the GenerateUI positive prompt and immediately applies them to the loaded workflow; shows a warning if no workflow is loaded in GenerateUI
• Tagger batch — Write .txt output — new output option that creates <filename>.txt alongside each processed image containing all generated tags (comma-separated)
• Gallery detail panel — Tagger button — new action button in the Gallery detail panel opens the selected image directly in the Tagger tab for instant single-image tagging
• Gallery detail panel layout — tabs (Info / JSON / Groups) and action buttons (Metadata / Load GenUI / Tagger) are now on separate rows, preventing button overflow on narrow panels
• Gallery — Save to Gallery tags fix — tags saved from the Tagger tab were stored as a string instead of an array, causing forEach is not a function errors on the next Gallery refresh; now correctly stored as a string array
• GenerateUI — ZIT/Lumina2 workflow prompt fix — ConditioningZeroOut removed from the CONDITIONING passthrough set; previously it propagated the "negative" role upstream through the shared CLIPTextEncode node, marking it as "unknown" and hiding the positive prompt in the GenerateUI Input tab; ZIT (Z-Image Turbo) workflows now correctly show the positive prompt
• Workflow analyzer — lumina2 model type — CLIPLoader type: "lumina2" is now correctly classified as Z-IMAGE in the workflow type detector

v0.3.37

• Models tab — Select All button — new button added to the right of "Deselect All" in the multi-select action bar; selects all models currently visible after applying the active search / filter / group filters
• Gallery tab — Select All button — new button added to the right of "Deselect All" in the bulk action bar; selects all images in the current folder view
• Gallery bulk bar — i18n — all bulk action bar buttons and the selection count were hard-coded English strings; they now use the t() translation system (EN / JA / ZH) so the bar respects the selected UI language

v0.3.36

• GenerateUI Save — overwrite protection — saving now checks for an existing file and asks for confirmation before overwriting; if the target file is in UI format, a dedicated warning explains that saving in API format will lose the node layout
• GenerateUI Save — Raw JSON sync — unapplied Raw JSON edits are now included in the save (parsed and synced back to the editor); invalid JSON aborts the save with an error instead of silently saving stale content
• GenerateUI Save — hardening — filename is set via DOM (no HTML-attribute injection), image extensions (.png etc.) are stripped from the default name, and a double-submit guard prevents duplicate POSTs
• Help i18n fixed — v0.3.35 help text updates (Save button, table sort, JSON tab rename) were being overwritten at startup by stale i18n strings and never displayed; all help keys synced in EN / JA / ZH and new entries registered in the help ID map
• Toast i18n — ~115 hard-coded English toasts replaced with translated messages (~60 new shared keys in EN / JA / ZH); Settings labels for Text Size / RAW JSON Colors that displayed raw key names are now properly defined
• Refactoring — new shared util.js (escapeHtml unified across 5 files — the Metadata tab copy was missing " escaping; readJsonStorage / getSettings replace 15 direct localStorage parses); Models table sort now precomputes sort keys (faster on large libraries); Gallery action buttons moved off the tab-button class, removing all !important CSS overrides
• README refreshed — intro rewritten around the three pillars (Management / GenerateUI / Library side panel); new screenshots: GenUI LoRA Stack, GenUI Batch, Models Multi-select Menu; WS Library image updated

v0.3.35

• Models tab — Table column sort — click any column header to sort ascending (▲), click again for descending (▼), click a third time to clear; active column name highlighted in accent color; Enable/Disable column header now labeled E/D
• Gallery tab — Load GenUI button — new button to the right of the Metadata button in the detail panel; loads the embedded ComfyUI workflow from the selected image directly into the GenerateUI tab; warning toast shown if no workflow is embedded or the format is unsupported; Metadata button restyled green, Load GenUI uses primary accent color
• GenerateUI tab — Save button — new button at the right end of the subtab row; opens a filename dialog (default: current workflow name) and saves the current workflow as a .json file to the Workflow tab via the import API; workflow name label updates to the saved filename on success

v0.3.33

• LoRA pane — workflow load no longer overwrites LoraManager — removed the auto-apply block that replaced inputs.loras / inputs.text with Stack group contents on every workflow load; Stack is now applied only when the Apply button is pressed
• LoRA pane — 🔄 button no longer resets to Single tab — active tab state is saved before innerHTML rebuild and restored afterwards; staying on Stack tab after refresh
• Models tab — Stack group hidden for non-LoRA types — when switching to Checkpoint or other non-LoRA types, the Stack group is now excluded from the group filter dropdown and side-panel group management (LoRA-only concept)
• CLIPTextEncodeEditPlus widget mapping fix — convertUiToApi no longer advances wIdx for UI slot inputs that have an actual link, preventing index misalignment when object_info lists optional STRING inputs (e.g. text1) before widget inputs (e.g. text_edit); fixes +af appearing as the positive prompt instead of the edit text
• Stack Apply — trigger words now applied correctly on first press — trigger words (currentAllTriggers / currentActiveTriggers) are now recomputed at click time from the latest _stackActive + metadata + civitaiCache; previously used a stale snapshot captured at render time, causing trigger words to be missing on the first Apply and to linger after disabling a model

v0.3.32

• Lora Loader (LoraManager) LoRA detection — I tab and Metadata tab now correctly detect LoRAs from Lora Loader (LoraManager) nodes in API format (inputs.loras.__value__); strength/clipStrength stored as strings (e.g. "0.20") are now parsed correctly
• LoraManager node placement — LoRA syntax — placing a Lora Loader (LoraManager) node via drag now also updates the text widget with <lora:name:strength> syntax (previously only the loras array widget was set)
• M tab Groups — LoRA → LoraManager drop — LoRA groups in the Library M tab show an All N LoRAs item; drag to canvas places a Lora Loader (LoraManager) node with all group LoRAs; double-click also places at canvas center
• P tab — Groups sub-tab — new Groups sub-tab (row 2) in the Library P tab; groups are read from localStorage["wfm_prompt_preset_groups"] (shared with Batch); expanding a group shows draggable preset items

v0.3.31

• LoRA pane — Single/Stack tabs — LoRA pane split into two tabs: Single (filter, model dropdown, M/C strength, target node, Apply, P, LORA SYNTAX, TRIGGER WORDS) and Stack (target node, Apply, P, Toggle-all, global strength adjuster, LORA SYNTAX, TRIGGER WORDS, model list); each tab has independent strength settings
• GenUI Model — LoRA improvements — now correctly handles Lora Loader (LoraManager) nodes (previously failed to find the node); on apply: switches to Single tab, disables all Stack models, and updates LORA SYNTAX / TRIGGER WORDS in the Single tab panel

v0.3.30

• LoRA Stack trigger words fix — inactive stack models no longer show their trigger words in the Trigger words display; both initial render and per-model toggle/toggle-all now filter to active models only
• Help troubleshooting — added entry for "No such file or directory" error when running LoRA Stack (comfyui-lora-manager compatibility issue)

v0.3.29

• LoRA section unified — single LoRA and Stack sections merged into one pane; Apply button handles both cases (stack models present → apply all active + prompt sync; no stack → apply selected single LoRA + prompt sync); Ctrl+Apply removed, now plain Apply by default
• LoRA prompt sync — Apply inserts <lora:stem:M:C> syntax and CivitAI trigger words into the Positive prompt; re-applying updates the prompt by diff (removes stale tokens, re-adds active ones); works for both single LoRA and Stack
• P button — placed to the right of Apply; immediately writes the current Positive prompt textarea to the target workflow node without switching tabs
• LoRA UI layout fixes — "Stack" label moved from ID row to Strength row left of the toggle-all checkbox; ID dropdown expanded to flex:1 (no max-width cap); M/C input width 54 px → 60 px to prevent value truncation
• Models tab — CivitAI default — side panel opens to the CivitAI tab by default when a model is selected
• Help tab — sidebar navigation — redesigned as 2-column layout: left sidebar (14 topics + Support fixed at bottom) + right content pane; content switches on click
• Input tab — Prompt/Image tabs + taller textboxes — Prompt and Image split into inner tabs; Positive prompt rows 4 → 8, Negative prompt rows 3 → 6
• Reset Workflow button — added to the GenerateUI toolbar; re-reads the loaded workflow file from disk and reloads the editor
• LoRA Stack trigger words — CivitAI trigger words for active stack models appended to Positive prompt on Apply; diff-updated on re-apply
• Feeder subtab UI — (root) folder selected automatically on tab open; PREVIEW pane moved to the far right of the layout; preview auto-updates to the current processing image during a RUN
• Batch tab — Sampler / Scheduler — left pane gains Sampler and Scheduler tabs (lists fetched from ComfyUI); Batch Queue gains two new columns; batch runs each value through KSampler sequentially
• Lora Loader (LoraManager) support — workflow analysis, single Apply, Stack Apply, and Batch all write inputs.loras.__value__ array + inputs.text syntax for LoraManager nodes
• Stack enable/disable — per-model checkbox and Toggle All checkbox; disabled models excluded from syntax/prompt; LoraManager apply preserves them as active: false
• Global strength adjuster — [−][step][+] controls for Model and CLIP strength applied to all stack models at once
• model-and-prompt-from-metadata node support — CLIPTextEncodeEditPlus, ImageMetadataCheckpointLoader, ImageMetadataPromptLoader, ImageMetadataLoRALoader added to workflow analysis
• Models thumbnail bug fixes — preview endpoint now sends Cache-Control: no-cache; files under 100 bytes skipped; .disabled model files included in preview change lookup

v0.3.23

• Bug fix: workflow batch 404 — _runBatchGenerate() workflow case was fetching /api/wfm/workflows/{filename} (non-existent route); corrected to /api/wfm/workflows/raw?filename={filename}
• Bug fix: rename double-submit — addEventListener("blur", commitRename) was accumulating on the persistent #wfm-modal-title-input element each time the modal opened; subsequent renames fired the handler twice, sending two rename requests back-to-back (first succeeds, second returns 409 or 404); fixed by storing the listener reference on titleInput._commitRename and calling removeEventListener before re-registering

v0.3.22

• Card view removed — Workflow tab and Models tab no longer offer Card view; Thumbnail and Table remain; if "card" was previously stored in localStorage it falls back to Thumbnail automatically
• Batch type selector — replaced the Checkpoint Batch toggle with per-type checkboxes on the Batch Queue column headers (Checkpoint / Lora / Prompt / Workflow); radio behavior ensures only one type is active at a time; the Batch panel below Generate repurposed as a status display showing the active type, amber progress bar, and Pause/Resume / Stop controls
• 4-type batch generation — _runBatchGenerate() dispatches to Checkpoint (file-tree + group selection), Lora (group selection), Prompt (preset group items applied to positive/negative nodes), and Workflow (group selection, restores original workflow after batch); all types use the same generic _runBatchLoop() with pause/abort support
• Help updated — EN / JA / ZH strings updated for helpWf1, helpModels2, helpGen11, helpGen13, helpGen14

v0.3.21

• CivitAI Host setting — new dropdown in Settings tab (CivitAI section): choose civitai.com (SFW only) or civitai.red (unrestricted); selection is saved to settings.json and synced to localStorage so the Models tab uses it immediately without extra server calls
• CivitAI panel — Info / Sample sub-tabs — the CivitAI side panel is split into two sub-tabs; Info tab contains model details and actions; Sample tab shows all sample images (count displayed in label); images open full-size in a new browser tab on click
• Bug fix: model page URL for existing cache — modelId: null entries (the majority of the cache) previously generated broken links (/models?modelVersionId=…); both the Python service and the JS renderer now fall back to /{host}/model-versions/{versionId} which redirects correctly to the model page; all 324 existing cache entries are fixed immediately without re-fetching
• Help updated — Batch tab entries (gen-12 / gen-13 / gen-14) and Settings entries (settings-11 Text Size / settings-12 RAW JSON Colors / settings-13 CivitAI Host) are now fully localized in EN / JA / ZH; helpGen3 updated to reflect 5-tab layout; helpGen11 rewritten to describe the Batch toggle; JA/ZH translations no longer contain untranslated English terms (Filter, Pause/Resume, Stop)

v0.3.20

• CivitAI panel — Type / Base Model / Hash display — side panel CivitAI tab now shows a Type badge (e.g. CHECKPOINT, LORA), Base Model row, and Hash row (BLAKE3 preferred, SHA256 fallback from CivitAI API or local metadata); click the hash to copy the full value to clipboard
• CivitAI panel — images open in new tab — sample images in the CivitAI tab are now wrapped in links; clicking an image opens the full-size version in a new browser tab
• CivitAI panel — 3-state UI — the panel now distinguishes between "not yet checked" (blue fetch button), "checked but not found on CivitAI" (re-check button with a notice), and "found" (full info); no more ambiguity after running batch fetch
• CivitAI tab click refresh — clicking the CivitAI tab in the side panel now re-renders its content, ensuring the latest fetch state is always shown without needing to reselect the model
• Bug fix: model page URL broken after batch fetch — the batch POST /model-versions/by-hash endpoint can omit model.id inside the version object; _extract_info now falls back to the top-level modelId field so the model page link is always correct; existing cached entries with a broken URL are also fixed client-side from modelId + versionId
• CivitAI cache — fileHashes field added — _extract_info now stores the primary file's full hash map (BLAKE3, SHA256, AutoV2, etc.) so the Hash row is populated for newly fetched or refreshed models

v0.3.19

• CivitAI batch fetch — major speedup — switched from one-by-one GET requests (0.5 s delay each) to POST /model-versions/by-hash batch endpoint; up to 100 hashes per request, reducing 100-model fetch from ~50 s to a few seconds
• Retry with exponential backoff — fetch_by_hash and the new batch POST both retry on HTTP 429 / 500 / 502 / 503 / 504 with 1 s → 2 s → 4 s delays (max 3 attempts), as recommended in the CivitAI API docs
• CivitAI API key support — optional Bearer token can be set in Settings tab (CivitAI API Key section); environment variable CIVITAI_API_KEY takes priority over the stored key; API keys are excluded from data exports
• Richer metadata — _extract_info now captures nsfwLevel (numeric), air (AIR URN identifier), stats (download count, thumbs-up/down), updatedAt, publishedAt, image dimensions / per-image NSFW level (imageDetails), and primary file precision / format (fileMeta)
• Hash consistency — cache keys use lowercase hex; API requests send uppercase hex as required by the CivitAI spec
• Bug fix: CivitAI tab blank after batch fetch — the done SSE event now applies data.hashes directly to state.modelMetadata so the side-panel CivitAI tab renders correctly even when the subsequent fetchModelMetadata() call races ahead of the server flush

v0.3.18

• Batch tab — new 5th subtab in GenerateUI with a dedicated 3-pane layout for assembling checkpoint batch queues; left pane: file-tree checkpoint selection (filter, All/None, initially unchecked); center pane: group-based selection with inner tabs (Checkpoint / Lora / Prompt / Workflow — Lora/Prompt/Workflow coming soon); right pane: live Batch Queue preview combining both pane selections with duplicates removed
• Checkpoint selector moved — the checkpoint dropdown is removed from the right panel; selection is now done exclusively in the Batch tab left and center panes; the right panel retains only the enable/disable toggle and progress display
• Group selection fix — batch group selection now stores selected group names (not raw model names), so changes to group membership in the Models tab are always reflected in the queue without stale entries
• Models tab bulk operations expanded — bulk action bar now includes: Deselect All (clear all selections without exiting select mode), ★ Favorite / ☆ Unfavorite, +Badge / −Badge (apply or remove a badge from all selected models); existing group and delete operations unchanged

v0.3.17

• CivitAI SSL fix — resolved CERTIFICATE_VERIFY_FAILED errors when fetching model info on Windows Portable Python environments; uses certifi CA bundle when available, falls back to system store, and disables verification only as a last resort with a warning log
• Lora Manager support — Lora Loader (LoraManager) nodes (ComfyUI-Lora-Manager) are now correctly converted from UI format to API format in the GenerateUI tab; the loras widget array is wrapped to {"__value__": [...]} as required by the node, enabling generation with LoRA Manager workflows

v0.3.16

• CivitAI preview fallback — model cards and the detail panel's Info tab now display the first CivitAI image directly when no local preview file exists; if the backend download fails (e.g. network restriction server-side), the browser fetches the image URL from the CivitAI cache as a fallback so the preview is always shown after fetching

v0.3.15

• Sample workflows — added workflows/ directory containing 13 sample workflows (SD1.5 / SDXL / DWPose / Face Detailer / Image Editing) with PNG thumbnails, bundled in the package
• CivitAI auto-preview — when fetching CivitAI info (individual or batch), the first CivitAI image is automatically downloaded and saved as {model_stem}.preview.png if no preview exists; batch summary reports the count of auto-saved previews
• TOOLS pane — Create Tags — new task option in the VLM dropdown (both SPA AI TOOL tab and Library A tab): generates a comma-separated list of descriptive English tags from the image

v0.3.14

• AI TOOL tab redesign — tab renamed from "A" to "AI TOOL"; sub-tab navigation removed in favor of a permanent 3-pane layout (Translation 40% | TOOLS 40% | Settings 20%) — all panes always visible simultaneously; "VLM" pane renamed to "TOOLS"
• Settings — RAW JSON Colors — new accordion section with 6 color pickers to customize the syntax highlight colors for the Raw JSON editor in Generate UI: Default Text, Name/Scheduler, Title, Width/Height, Prompt/Text, Image/File; changes apply immediately on color pick; Reset Defaults restores the original scheme; saved to localStorage under wfm_settings.jsonColors and applied on startup
• Help tab updated — AI TOOL tab card rewritten; Settings card updated with RAW JSON Colors entry; Library panel sidepanel-16 entry updated

v0.3.13

• AI Tab (A) — new tab added to both the SPA and the Workflow Studio Library side panel (rightmost tab)
  • Translation sub-tab — translate text via Ollama or LM Studio between Japanese, English, Chinese, or a custom Free language; ⇄ swap button exchanges both language selectors and text content simultaneously; language selections persisted automatically
  • VLM sub-tab — drop zone (110px, matching the I tab) accepts images via drag & drop or click; task selector (Describe Image / Create Prompt); Run button streams result into output area with Copy button; Ollama uses images:[base64] payload, LM Studio uses image_url content block
  • Settings sub-tab — backend radio (Ollama / LM Studio), API URL input, connection test with live status, model selector with refresh, Free language name fields (source and destination); saved to localStorage key wfm_ai_settings and shared between SPA and Library panel
  • URL security — backend URL validated via new URL() to enforce http:// or https:// scheme before any network call
• Settings Tab — Ollama section renamed — "Ollama 設定" → "Ollama 設定（プロンプトタブ）" to distinguish it from the new AI tab's settings
• Help Tab updated — added AI Tab (A) feature card and Library panel A tab entry; i18n support in EN/JA/ZH

v0.3.12

• GenerateUI — Raw JSON search — always-visible search bar above the Raw JSON editor; finds all matches as you type with match count (3/12); navigate forward/back with ↑/↓ buttons, Enter / Shift+Enter, or Escape / ✕ to clear; current match highlighted in orange, other matches in yellow; search overlay syncs with editor scroll and stays updated while editing
• Workflow analyzer — extended model type detection — added CLIPLoader type field mapping to model family (flux, hidream_i, wan, cosmos, lumina, ovis, etc.) via _CLIP_TYPE_TO_MODEL; subgraph nodes (definitions.subgraphs) now scanned for model detection; UnetLoaderGGUF and similar loaders matched via "UnetLoader" in ntype; new families added: NewBie, Ovis, HiDream, Wan, Cosmos, Lumina; model-name detection refactored into reusable _detect_model_type_from_name()
• Screenshots refreshed — replaced tab-by-tab screenshots with 8 feature-focused images

v0.3.11

• Metadata Tab — extended loader support — metadata-tab.js now recognizes UnetLoaderGGUF and UNETLoaderGGUF as Diffusion Model (e.g. HiDream GGUF workflows), and QuadrupleCLIPLoader as Text Encoder (e.g. HiDream 4-CLIP); previously these were detected only in the side panel I tab, not in the Metadata tab itself
• Settings Tab — Text Size — new slider (10–28 px) in the Settings tab adjusts font size for all prompt and chat text areas at once: Generate UI positive/negative prompts, AI Assistant chat input, Preset prompts, Wildcard text area and file editor, and Metadata prompt full preview; applied immediately on drag and persisted with Save Settings

v0.3.10

• Information tab — drag to canvas — model, lora, and Prompts sub-tabs in the side panel I tab now support drag & drop onto the ComfyUI canvas; double-click also places nodes at canvas center
  • model sub-tab: each item places the corresponding loader node (Checkpoint → CheckpointLoaderSimple, VAE → VAELoader, Diffusion Model → UNETLoader, Text Encoder → CLIPLoader)
  • lora sub-tab: drag individual LoRA to place LoraLoader; Multiple LORA section (shown for 1+ LoRAs) places all LoRAs in a single Lora Loader (LoraManager) node
  • Prompts sub-tab: drag a prompt to place CLIPTextEncode with the full text pre-filled
• Extended node type support — UnetLoaderGGUF / UNETLoaderGGUF now detected as Diffusion Model; QuadrupleCLIPLoader (HiDream and similar 4-CLIP workflows) now detected as Text Encoder
• Bug fix: CLIPLoader widget name — textencoder type in MODEL_NODE_MAP was incorrectly using clip_name1 (DualCLIPLoader's widget) instead of clip_name; Text Encoder models now drop with the correct filename
• Preview area fixed height — Information tab drop zone fixed at 110px so model/prompt lists are no longer compressed when a large image is loaded

v0.3.9

• Side panel I tab — new Information tab in the Workflow Studio Library side panel; drop a ComfyUI PNG/WebP/JSON directly in the panel to inspect models, LoRAs, and prompts without opening the Metadata tab; sub-tabs: model / lora / Prompts with full-text preview and Copy button
• Side panel tab redesign — tabs shortened to single letters (W / N / P / M / I) with full name shown on hover
• Bug fix: top bar icons — icons (Workflow Studio / camera / Node Sets) were invisible in newer ComfyUI versions because Iconify converted the MDI CSS class to an inline SVG before the custom SVG could be injected; fixed by removing the early-return guard and adopting the same simple requestAnimationFrame retry pattern used by lora-manager

v0.3.8

• Metadata Tab: extended subgraph support — added extraction for Flux.2 Dev fp8 (SamplerCustomAdvanced), Flux.2 Klein 4B Distilled (image edit), Ernie Image, Qwen-Image-Edit 2511 (TextEncodeQwenImageEditPlus), and WAN2.2 14B Animate (top-level CLIPTextEncode + subgraph KSampler)
• Prompt type: Text (no badge) — when positive/negative polarity cannot be determined (indirect sampler connections, cross-level links, PrimitiveStringMultiline etc.), prompts are listed without a POS/NEG badge; action buttons still work normally
• Prompt extraction improvements — extractPromptsFromNodeSet now resolves link sources from any STRING-output node (e.g. ComfySwitchNode, PrimitiveStringMultiline) without type restriction; PrimitiveStringMultiline search and final text-encoder fallback both extended to include subgraph nodes via collectAllNodes
• i18n — added metaPromptText key (EN: "Text" / JA: "テキスト" / ZH: "文本")

v0.3.7

• Metadata Tab: subgraph workflow support — Flux.2 (Dev fp8 / Klein), Qwen-Image-Edit (/ 2511 / Layered), and Z-Image (Base / Turbo) official templates now correctly extract models and prompts; these use ComfyUI's definitions.subgraphs format with UNETLoader, CLIPLoader, and VAELoader inside the subgraph
• Prompt extraction improvements — 7-stage fallback chain: ImageMetadataPromptLoader → WFS_PromptText → top-level CLIPTextEncode+KSampler → PrimitiveStringMultiline (flux2-klein) → subgraph CLIPTextEncode+KSampler → PromptStyler → all CLIPTextEncode text
• MarkdownNote model fallback — extractMarkdownNoteModels() parses **section** → - [model](url) patterns from MarkdownNote nodes as a supplemental model source
• Format note updated — "Flux.2 / Qwen-Image / Z-Image subgraph workflows supported" (EN/JA/ZH)

v0.3.6

• Metadata Tab — new tab (between Prompt and Gallery) that extracts model and prompt information from ComfyUI-generated PNG/WebP images and workflow JSON files; 3-column layout: drop zone with image preview (left), Checkpoint/VAE/Diffusion Model/Text Encoder lists (center), LoRA list with strength values + Prompt list with full-text viewer (right)
• Prompt action buttons — Copy, GenUI:P/N (set GenerateUI prompts), Prompt:P/N (set Prompt tab preset prompts) directly from the extracted prompt text
• SDXL Prompt Styler support — improved prompt extraction resolves PromptStyler → CLIPTextEncode link chains in both LiteGraph and API workflow formats
• Format support — ComfyUI (PNG/WebP/JSON), SD WebUI, SD Forge, Fooocus

v0.3.5

• Feeder subtab — new subtab in GenerateUI for controlling comfyui-image-feeder nodes; left pane: node selector + all ImageFeeder parameters + presets + Run/Stop controls; center pane: folder tree, image grid with checkbox selection, and preview panel
• Run loop with After gen modes — Loop (wrap and continue), Increment (advance and auto-stop), Fixed (constant index); index updates automatically via WebSocket image_loop_node_sync after each generation; seed comes from the right-pane seed setting
• Workflow analysis improvements — analyzeWorkflow now handles multi-hop CONDITIONING chains via BFS (up to 5 iterations), CLIPTextEncodeSDXL / CLIPTextEncodeSDXLRefiner, SDXLPromptStyler / SDXLPromptStylerAdvanced, KSamplerAdvanced (noise_seed), TextEncodeQwenImageEditPlus, PrimitiveStringMultiline, Power Lora Loader (rgthree), and Checkpoint Loader (WAS) with space in the class name

v0.3.4

• Wildcard support panel — new right column in the Prompt tab with a one-click toolbar for inserting wildcard syntax ({|}, {n$|}, __|__, :, ;, $, <lora::1:LBW=;>, [], single/multi pick) and wrapping selected text; dedicated prompt textarea and wildcard file picker (click to insert __filename__)
• Wildcard file manager — create, view, edit, and delete .txt / .yaml wildcard files stored in user/default/Workflow-Studio/wildcard/; editor opens inline with filename input and save/cancel controls
• Preset/Preset Manager tab switch — the center pane of the Prompt tab is now a two-tab panel (Presets / Preset Manager) to reclaim horizontal space for the new wildcard panel
• Wildcard Integration setting — new accordion section in Settings tab; auto-detects ComfyUI-Impact-Pack; when installed, provides a button to create a directory junction (Windows) or symlink (other OS) from the WFS wildcard directory to Impact Pack's wildcards/ directory; existing WFS files are migrated automatically; a Remove Link button reverses the operation

v0.3.2

• Checkpoint Batch — new panel in the GenerateUI right column (below Seed, above results); enable via checkbox to auto-generate once per checkpoint model; filter included/excluded subfolders by comma-separated names (empty = all checkpoints); real-time preview of matched model count; amber progress bar shows current model name and index; Stop button aborts the loop after the current generation completes; failed models are counted and reported in the summary toast
• Seed layout fix — seed value input and mode selector (Random / Fixed / Increment / Decrement) now stacked vertically so neither is clipped in narrow panels

v0.3.1

• Folder operations — create subfolders and delete folders (with all contents) directly from the folder tree header buttons
• File operations — move or delete individual images from the detail panel; bulk move and bulk delete from the multi-select bar
• Tree state preserved — folder expansion state is maintained after create/delete/move/refresh operations
• Workflow viewer improved — Metadata tab now reads both prompt (API format, the default for most ComfyUI-generated images) and workflow (UI format) keys from PNG metadata, covering virtually all ComfyUI output
• Workflow auto-save — after each generation in the Generate UI tab, the current workflow is automatically saved to gallery metadata for the generated images; shown in the Metadata tab even if PNG embedding is absent

v0.3.0

• Cross-type group filter — the group filter dropdown in the Models tab now shows groups from all model types simultaneously, each prefixed with a type label ([Checkpoint], [LoRA], etc.); selecting a group automatically switches to the corresponding model type
• Sidebar group display fixed — the ComfyUI sidebar "Model Groups" view now correctly renders per-type groups (introduced in v0.2.9) with a type label on each group header; fixes a crash where .filter is not a function was thrown on the new nested group structure

v0.2.9

• Model Enable/Disable — hide models from ComfyUI by renaming the file extension to .disabled; toggle per model (⏸ button on each card/row), per group (Enable All / Disable All buttons in the Group panel), or filter the grid by status (All / Enabled only / Disabled only). Changes take effect after ComfyUI refresh.
• Per-type model groups — groups are now scoped to each model type; checkpoint groups only appear in the Checkpoint tab, LoRA groups only in the LoRA tab, etc. Existing flat groups are automatically migrated.
• Multi-select mode — click the Select button in the toolbar to enter selection mode; check individual models across Thumbnail / Card / Table views
• Bulk group operations — with models selected, add or remove them from any group in one click, or create a new group and add them simultaneously
• Bulk file delete — permanently delete selected model files along with all associated preview images and sidecar files (.json, .civitai.info, .info); requires confirmation before deleting
• Bug fix — models in subdirectories could not be disabled due to a path-doubling error; fixed by computing the rename target from path.name instead of model_name
• Bug fix — Hypernetwork tab showed C, O, M, B as fake model items; caused by the new ComfyUI API format returning "COMBO" as the first element; fixed in comfyui-client.js

v0.2.8

• Data storage moved — plugin data (settings, metadata, prompts, etc.) is now stored in ComfyUI/user/default/Workflow-Studio/ instead of custom_nodes/ComfyUI-Workflow-Studio/data/; falls back to the old data/ directory if user/default/ does not exist
• Data Management section — new Settings tab section to export all plugin data to a single JSON file and import it back; useful for migration, backup, and reinstallation

v0.2.7

• Gallery tab — new image browser for ComfyUI output folder; Thumbnail/Table views, multi-select with Bulk Bar, server-side group/tag/favorite filtering, group management (rename support), performance-optimized with + mtime folder cache
• Group UI unified — Workflow, Nodes, and Gallery group panels rebuilt to match the Models tab 4-section pattern (Current Groups / Add to Group / Create New Group / Manage Groups); Rename support added to Workflow and Nodes tabs
• Settings 2-column layout — Theme panel fixed on the right (50% width, sticky); all other settings flow continuously on the left with no visual gap
• Gallery output directory setting — configure the output folder scanned by Gallery tab from Settings
• Help tab — Gallery tab description card added

v0.2.5

• Sidebar Category/Package sub-tabs — added 📂 Category and 🧩 Package sub-tabs to the Nodes tab in Workflow Studio Library; each shows a dropdown to filter nodes by category or custom node package (reads /object_info for accurate package detection)
• Sidebar theme settings — added ⚙ button in the panel header to customize background, sub-header background, text, border, and secondary text colors with live preview; settings saved to localStorage
• Sidebar TextEncoder (By Type) — fixed TextEncoder not appearing in Models → By Type; now uses DualCLIPLoader → CLIPLoader fallback to retrieve clip_name1 list
• Hide .index.json — excluded .index.json from both the Workflow tab and the Workflow Studio Library side panel

v0.2.4

• GenerateUI tab redesign — reorganized from 5 tabs (Prompt/Image/Model/Settings/Raw JSON) to 3 tabs (Input/Model/Settings); each tab shows a Raw JSON column (540px) for instant JSON preview and direct editing from any tab
