widget bar, game or app

i was thinking about the widget bar and i know ive read on here somewhere that there might be an update for different and new widgets, but do u think they'll make one for a game or application. Ive changed my phone to be able to minimize games instead of just exiting out, but it would be cool to be able to stick it on the widget bar to be able to get to it faster later. Just thought id ask if that was at all possible and if maybe samsung will make it on the update?
