- Video thumbnails: try ffmpeg, fall back to play icon placeholder
- Right-click no longer restarts video playback on same post
- Reset activated index on new search
- Missing file indicator (red dot) for NAS/lost files, QSS-controllable
via qproperty-missingColor
- Library items now show green saved dot
- Missing files detected on refresh and marked red
Library now generates video thumbnails by extracting the first
frame with ffmpeg. Cached alongside image thumbnails. Falls back
gracefully if ffmpeg is not available.
- Videos show a play triangle + file extension as placeholder
- Multi-select right-click: bulk delete from library
- Image thumbnails confirmed working
- Image thumbnails generated via PIL and cached
- Video files show tooltip with filename (QPixmap fallback attempted)
- Right-click: Open in Default App, Open Containing Folder,
Copy File Path, Delete from Library
- Skip video files in library thumbnail generation (PIL can't open them)
- _on_bookmark_done only sets bookmarked for bookmark ops, saved for save ops
- Smaller green dot with yellow star to its right
- Default bookmark star color: yellow (#ffcc00)
Major restructure of the favorites/library system:
- Rename "Favorites" to "Bookmarks" throughout (DB API, GUI, signals)
- Add Library tab for browsing saved files on disk with sorting
- Decouple bookmark from save — independent operations now
- Two indicators on thumbnails: star (bookmarked), green dot (saved)
- Both indicators QSS-controllable (qproperty-bookmarkedColor/savedColor)
- Unbookmarking no longer deletes saved files
- Saving no longer auto-bookmarks
- Library tab: folder sidebar, sort by date/name/size, async thumbnails
- DB table kept as "favorites" internally for migration safety
