support android "back" button/function
it is annoying when the back key from android devices is not supported. quitting dialogs, canceling inputs etc... should easily be doable through the android "back."
I haven't voted in either direction. But I agree in some way, though I am reluctant to vote for it as I know from my professional work that his might cause unwanted side-effects.
To name one (which is IMHO key): Redundancy. I am a strict advocate of uniqueness if it comes to UI design.
Please do not take this as an argument against the proposal, but you/we should carefully think about side effects.
It is probably a good idea to let the user activate it or not by configuration.
