@Emil The most important thing for me is getting Twist functionality for LIFX Cloud working, since LIFX LAN only shows 2 out of my 7+ lights and does not seem to work (and may or may not work with groups / scenes).
Another interesting feature (not a priority) would be the option to allow one button to manage several controls by toggling through them, perhaps setting different color LEDs for each function. IE if I double tap my button, first the twist does LIFX brightness, then I double tap again and the twist changes to control color, double tap again and maybe it controls that room's Sonos volume, etc etc.
