I'm very disappointed in the 9.2 update to the windows controller. I don't care so much about the colors (although they're terrible) but the layout is broken. It won't save the size and location of the window and it's a real PIA to reset every time I open it. The layout has a lot of wasted space that could be better used for album art, better icons to click on for repeat/shuffle, etc. There is a lot of room for improvement that I don't see happening every time we get an update.
And when will Sonos do something about the volume slider in the apps? It's nearly impossible to fine-tune the volume level. Please add a clickable +/- or something to allow volume change by tiny amounts, in increments similar to the hard button on the speaker itself. At night listening in bed a tiny volume adjustment can make a huge difference in comfort level and that slider just doesn't work well.
