Ability to pin artists / albums / playlists / tracks
It was suggested on Mastodon:
As for the feature request: The ability to pin artists, playlists, albums, songs etc. Basically like the recently favorited section except with items that will always remained pinned on the main library page. Reason for this being is I have certain albums that I want to always be able to reach no matter what radio or playlist I'm listening to at that moment
Another option would perhaps be having the pins be pinned to the top of their respective sections, but personally I feel having a "pinned" section would be better
