Recently picked up on Chunithm after a trip to Japan and I've been wanting to rebuild my favorites list but unfortunately the option was missing from aqua-viewer, after a bit of looking around the code I managed to add a simple version of it.
I've only spent a few hours on this on a completely alien codebase in a language I never use, so if I did something super stupid please tell me and I'll try to fix it.
When I say rudimentary, I mean:
It'll not stop you from pressing the button if there are > 50 songs in your favorites (which is the limit from what I've read)
There is no list to easily see all the songs you have favorited, so you have to find them again in the song list/database
Additionally, since I'm only interested in New+, the code will only work with Chusan
For the function itself, it is present on any music detail page and looks like this (ignore the missing picture):
