Hi,
So this might be just me and my OCD but, I’d really like a (mostly pointless) feature within the controller apps to be able to click a button (double-tap or something, I’m not saying _how_ it should be done) and have all the volume levels lined up across all grouped speakers.
When the family all leave the house and it's just me home, I like to crank up the volume across all speakers but the thing that I find annoying (it really is trivial) is having the volume levels not quite all the same. Forget the relative volume of each speaker, I just want to have the levels all lined up.
Cheers
