Sometimes a jailbreak tweak comes along that is so subtle and yet so brilliant. Banner notifications in iOS are great, but Apple made a poor design choice: incoming banners push in on the top of whatever app you’re using at the moment. If you’re using Safari, the address/search bar is momentarily obscured by a banner notification. That’s no good.
A new Cydia tweak called CoverMeNot keeps banner notifications out of the way by automatically doubling the height of your iOS status bar. No more obtrusive banners covering the top of your favorite apps.
