I think it would be amazing if the app could store different settings for Music audio vs Theater audio, specifically the bass level.
One of my favorite features about Sonos is that it can tell between just audio playback versus using my theater system and changes my settings on my play ones to rears automatically.
In my case, one thing that I have found is that when the theater setting is on the bass is too loud for movies, but I prefer the bass to be louder during music
