Great idea. Downloaded. Moved 2 apps to SD, then checked out list for SD to Phone (nothing moved, just looking around) and got a FC. Will keep for a while to check out future updates.
Ideas for future:
-app icons (so you can tell WHICH angry birds app you're moving )
-file size before / after move
-total available space
-multi-select (something that would GREATLY improve the app over settings)
