Hello! My whole family loves Sonos. We do find setting and normalization of volumes to be a challenge, however: once we get volume "just right" it's hard to get it back once we've ad-hoc upped or lowered volumes in the various rooms.
I'd love to see some (non-geeky, subtle) way where a numeric indicator of volume (0-100?) could be surfaced in the Sonos app, so it would be easier to get the volume levels right and reset them to favorite settings as well. As it is, the sliders available in most apps give convenient control, but it's very hard to use them to reproduce sound settings on the fly. I've used python libraries like SoCo to get and set these volumes, but that's not a method that most users would be able to refer to.
Thanks for considering!
