Add artist favorite
What is the problem you are facing?
Funkwhale misses a feature that I find pretty useful in Deezer and Spotify.
On these platforms, it happens somewhat frequently for me to browse my liked artists, searching for a mood music (e.g. "am I more in a Radiohead or a Die Antwoord mood today?"). Then when I know, I select the artist and browse its albums and choose one to play.
Also, thank to that, I get notifications when a new album from one of my liked artists arrives on the platform. Funkwhale could definitely have that too. It would be a nice way to notify your users that a new album, from an artist they like, has been uploaded.
What are the possible drawbacks or issues with the requested changes?
I don't see much... but I'm still getting used to Funkwhale.
Maybe a potential issue with the federation?
Both pages are accessible through an entry in the left menu ("Albums" for Deezer, "Library" for Spotify), and then "Artists" in the top menu. I would personally prefer to have "Artists" directly accessible from the left menu.
