[Feature Request] Adding filter database by album artist and sorting by track number

[DestroyerAce]

I'd like to suggest a few enhancement for termusic that would greatly improve the user experience when browsing through albums and tracks.

1. Being able to filter database by album artist tag
   I use musicbrainz picard to tag my songs which make artist tag of songs with multiple artists look like "Artist 1 feat. artist 2" which makes them show up multiple times in database when filtering by artists. So, if there's an option to filter by album artist, it will stop same artists from showing up multiple time.
2. Sorting tracks section with track number
   Currently tracks section sort the tracks by alphabetical order which makes playing albums in order kinda hell.
3. Album column and showing whole album as entry in search dialogue box thingy

All the features mentioned above will greatly improve navigating and adding albums to playlists a lot easier and better for users.
