Or perhaps, at the very least, automatically go to the app menu for all apps that are already open, but require activation for those that aren't?
Ideally switching to any open (or not) app would be as simple as: [menu, left, (up,down)*, play], at which point the RB menu would fade away, leaving the newly selected behavior's controls active.
