Also, lets say you want to rearrange the keys at the bottom. I like Moto and Samsungs layout over htcs and the previous nexus's layout. You might be able to map where the menu, home, back, and search keys are or even change them completely. Lets say you don't use the search key for some reason, you might be able to change it to an app you use more often. The possibilities are endless with what you might be able to do with ics. We just have to wait and see. I really doubt Google will let us down.
