OMG you guys are all crazy, That's the icon for Connected Display Settings. It will function on the Slim, But as of now it is visible on the Phat for some reason..
It's okay, Just don't use it..
This is the first theme so far to include the Connected Display Settings Icons, Most themers don't have a slim.. So it was bound to cause some strange things.. It's in the vshmain I think but it works fine.. It won't work on a Phat.. But it's just there so it will be should you have a Slim.
