- Editable label combo with DB history (most recent first) - Click marker to arm overwrite mode (↺ indicator, re-exports same file) - Portrait crop overlay: red bands on cut regions (paused only) - Cache video dimensions to avoid mpv property reads in paintEvent - Queue marks done files with ✓ on drop and after export - Export folder created automatically if missing - Play continues from new position when scrubbing during playback - Counter auto-advances past existing files on disk - Instant marker on timeline when export starts (optimistic) - Marker right-click delete Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
