ComfyUI-Drag-Ghost 👻

A premium visual enhancement for ComfyUI that adds a smooth "ghost" effect when dragging nodes and groups. This extension significantly improves the user experience by providing clear visual feedback, performance optimizations, and advanced handling for complex workflows.

✨ Features

🚀 Visual & Performance

• Smooth 60 FPS Rendering: Uses requestAnimationFrame for buttery smooth dragging, even in massive workflows.
• Ghost Previews: Shows a semi-transparent "ghost" of your selection (nodes and groups) while dragging.
• Grid Snapping: Real-time visual snapping to the grid for precise alignment.

📦 Configuration

🎬 Example

📦 Advanced Group Support

• Synchronized Movement: Moving a generic group automatically moves all nodes inside it.
• Mixed Selection: Seamlessly drag a combination of individual nodes and groups.
• Smart Ghosting: Optimizes performance by rendering the group container instead of every individual node inside it.

📌 Pinned Node Safety

• Visual Feedback: Pinned nodes appear in RED to indicate they are "stuck".
• Respect Pinned State: Configurable setting to prevent pinned nodes from moving during a collective drag.
• Drag & Drop: If "Respect Pinned" is disabled, pinned nodes will move but still show as red for awareness.

🎨 Customization

• Border Styles: Choose from Solid, Dashed, Dotted, Double, or None.
• Custom Colors: Pick any color for your ghost via the settings menu.
• Theme Integration: Works out of the box with the default dark theme.

⚙️ Settings

You can configure the following options in the ComfyUI Settings menu (Comfy.NodeGhost):

• Enabled: Toggle the extension on/off.
• Border Style: Change the ghost border style.
• Border Color: Select a custom color (HEX) for the ghost.
• Respect Pinned Nodes: If enabled, pinned nodes will stay in place when dragging their group or selection.

📥 Installation

1. Navigate to your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes/
   

2. Clone this repository:

   git clone https://github.com/GalactusX31/ComfyUI-drag-ghost.git
   

3. Restart ComfyUI.

🛠️ Logic & Behavior

• Cancel Drag: Press ESC key to instantly cancel a drag operation and revert everything to its original position.
• Safety Checks: Dragging is disabled when holding modifiers (Ctrl, Shift, Alt) to allow native ComfyUI functions (like cloning) to work without interference.
• UI Protection: Prevents accidental dragging when interacting with sliders, text fields, or connection slots.
