I agree....the SONOS app is much better than the C4 UI. Especially with the recent change that allows single touch playback. In C4, you still have to drill through about a billion submenus to get something to play. And with the auto room on/off feature still in the endorsed driver, it makes it easy to track zone status, etc.
