Have you played EA's The Simpsons Tapped Out on the iPhone? I think that would be the perfect interface for the home screens instead of the boring grid of icons on iOS. A continuous isometric 3-d plane. I have a good hundred buildings on my game and can get to them very quickly because I recognise landmarks on the "map" and know where buildings are located. Surely this is the way forward - it would also bring back a bit of fun to the iOS interface.

That's for you
