I did some prototyping this morning.

For some reason, Android only allows a max of 3 buttons in the notification area...not sure why they did this, but I'm not very happy with it. If you were only given 3 buttons, what would you have each of them do?

The rest of the notification stuff is done

As for gesturing, it's easy enough to accomplish on its own, but cannot be combined with the pager view I already have in place (the swiping back and forth between remote and playlists) so I am not sure how it could be implemented. Perhaps a 'car mode' screen...
