Hey all,

I basically do the sort of thing you're discussing in this thread with my iSwap app. It allows for more than 1 screen of icons that you can swap back and forth at the touch of a button.

Here's a video of it in action:

It's available in the d/l section or there's a link to my blog off the video with a different d/l link. Also, I'll be releasing v.2 with unlimited expandability in the near future.

Cheers!
