 # Todo
+- [ ] Fix bug that causes Make Default Tracks First to delete single, non-default tracks
 - [ ] Make Anime Subtitle Fixer have an option to exclude titles when counting (this is hardcoded right now)
 - [ ] Investigate using mkvmerge instead of ffmpeg in Set Subtitle Dispositions By Title to stop increase in file size (https://www.reddit.com/r/ffmpeg/comments/wsogpl/removing_subtitle_track_results_in_a_bigger_file/)
 - [x] Plugin to strip PGA subs if ASS exists
