- 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
