I am running a stock N1 and Galaxy Tab and have just discovered Launcher Pro. The description in the Market is a little sparse so I would really appreciate some help with a few questions before I install it. First, will it 'damage' the OS on the phone? Meaning if I choose to remove it will it come out cleanly without me needing to rebuild my devices. Second, what will it really let me customize? Finally, is this the best option for changing your home screen? Thanks.
