This is something that I have been thinking for a while now, when running full screen games/apps (full screen as in no iPad, wifi signal, time, battery) to totally disable any notification popups. It is very off putting when playing a game when a notification comes onscreen halfway through playing a game, you take your eyes off it for a split second and that's it. I think if it was to be implemented it would needs its own section in the settings so you could toggle all the different apps and also have a main on/off switch. What are your thoughts on this? I appreciate that the iOS 5 notifications aren't as intrusive as iOS 4 and previous versions, but they do still take your eyes off the game! I also understand that the idea of notifications is so that you are always in the know.
