🐯 YFG Random Prompt From File
YFG Random Prompt From File (v1.1.0) Selects a random prompt from a .txt prompt file. File format: positive: your positive prompt negative: your negative prompt (empty is fine) name: optional label (defaults to filename) ---- (any number of hyphens as separator) range_start / range_end auto-fill when a file is selected. Toggle last_n_only to restrict picks to the newest entries. INDEX auto-syncs after every run — switch to by_index with no typing.
