I added the zap button functionality to take me back to the root activities menu. Running the test/preview shows that it will actually take me back to the root menu, but it won't let me select an activity after that unless I power on and off again.
Also, is there anyway to add this functionality at the "processor" or highest level like the Power On button in the Shortcut activity? I'd like to avoid re-binding the Zap button for every activity and menu.
