Mac menu bar volume controller
The Mac version of the controller is great but doesn't really try to integrate with the Mac OS UI. If I have several windows open on my laptop screen, I find it very annoying that I cannot control something as basic as the volume of a Sonos zone from the Mac menu bar. There are several other ideas I could think of to make the Sonos controller more usable for Mac users (a dashboard widget, a quicksilver plugin etc, custom keyboard shortcuts), but just a simple volume control would be a major breakthrough and probably not very difficult to implement as most controller functionality is directly accessible from the dock's contextual menu.
