[Feature Request] additional configuration for `misc.lua` and some questions

[WhoMI7]

1. Font, font size, spacing, display duration, mediainfo format (Instead of Default N:, G:, V:, A:, S:) Name:, G(idk what G stands for):, Video:, Audio:, Subtitle: looks better.
2. cycle-known-tracks audio should show Audio: (ID) lang instead of aid: (ID) lang same for cycle-known-tracks sub.
3. cycle-known-tracks audio up and cycle-known-tracks audio down and same for cycle-known-tracks sub(Why wasn't this implemented before? Since this is available in almost all media players).

Also some questions:

1. How do quick-bookmark work? why does it save it in .mp4 extension, how do I load a bookmark simply from mpv and without opening the file explorer?
2. If it can't load directly from mpv then what's the point of it having it over quit-watch-later?
3. can quick-bookmark bookmark .m3u playlists? Like If a playlist has 50 files and I am on 5th at 0:27:07 so if I load bookmark it loads .m3u playlist with file number and position intact or just that particular file?
