Feature: Subtitles section

[TriVoxel]

Please add a section which lists the subtitle tracks to they can be re-organized, removed, and new sub tracks can be added from SRT files, and offsets can be adjusted. This is useful for many applications. In FFMPEG, this can easily be done with the -map feature with very minimal performance hit.

This is definitely out of reach for a developer of my competence level when it comes to libadwaita. I'm going to keep this open and encourage someone to make a PR if they believe this could be implemented.
