We have our TV as a dual screen to use xbmc on - would I be able to play games on that screen with this or would they just default to the monitor (#1) like they usually do?
Also agree that it would be a good idea to only show controller enabled games, it's a bit pointless having a 'kick back in the living room' steam that still needs m&k/b for games.

Also the ability to shut down the PC from within the big picture UI would be sweet, saving the hassle of getting up and shutting down from the PC.
