I have a couple of android tablet mounted to my wall as home controllers running your Andoird app. There are some simple things that I would like to see changed:
1. When a disconnect happens, change the boarder color to red and try to automatically try to reconnect indefinately (it would resume the black border when connected). I could see this as bad for a phone, but an option like "use dialogs" to put it in this mode would be good. I have to go to the tablet and press a dialog every time I restart my axial server or restart my router.
2. An indication that a device communication has failied. Maybe put an asterick on a button to inidcate that a device or subdevice has failed communication and what you are looking at is not accurate.
3. Lock scrolling. Sometimes I try to press a buttion and my finger slides a little and it is rejected as a scroll event. This would even be more useful as a quick button on the red bar.
