Some features I've had in mind that'd be sick:
1. More advanced notification options
ie volume ducking (w/ & w/o a notification sound)
2. server/config backup options
for me, i'd like server backups, but the whole app's config would be nice. I'm constantly flashing new roms on my phone and having to resetup my two servers
3. Reset play settings after server change
i'm referring basically to repeat. after a server change, it should go back to no-repeat.
4. Share 'Now Playing'
add the share icon to now playing and send a subsonic share link to whomever.
don't know the feasibility of this one (especially with the apparent lack of a mobile player on web-based subsonic...), I just have had this list open for a few days and wanted to add a fourth haha
obviously, thanks for all the hard work!
