I broke down and installed installer.app and Summerboard. It's kinda fun. But I miss the home screen icon transition when starting an app or going back to the home screen. The default is a zooming effect...with Summerboard, it's sort of a boring slide up/down effect. I don't see anywhere to change that. I wonder if it's because the normal zooming effect is a fixed image of the home screen with the stock icons. Guess it would be pretty hard to replicate with custom icons. Anyone know?
