Myself, along with many, have been annoyed that when playing a game it is easy to mistakenly swipe the notification center down. In the new beta, when you're in a game in landscape, the first pull down only brings up the the little "tag" (for lack of a better word) and the second pull brings down the whole notification center! This function seems to almost have AI because I could not replicate it in stock apps like messages and email. Also, if you don't do the second pull after 2-3 seconds the "tag" disappears. Check it out (tag): Pretty sweet!
