Does anyone know if there's a centralized notification system implemented that's much more forgiving of taking over the screen (much like Android?) I hate having to hit view or close while i'm in another application and I get say, a Push Update from Words With friends. I wish it was less intrusive and just hovered at the top until I wanted to take care of it.
