I don't want it updated, seeing the current app that's public is... rather useless, seeing what's there can be seen on screen. Any G15 app is useless for games, becuase why are you looking at your keyboard, rather than at the monitor?
What'd be more useful, is an app that ran in the background, telling you if a user from a personalized list of users joined a server, because then you could go "Oh, Sam's being a sexy beast and going into Race 2, maybe I should go give him some teamly wrecks", rather than "OMG! I'M GOING 200 MPH, I'M LOOKING AT MY KEYBOARDS LITTLE LCD SCREEN RATHER THAN THE MONITOR! OH NOEZ, I'VE JUST WRECKED EVERYONE LULZ"
Just my logical 2 cents.
