But I think I found a small bug in skinning mode. It's a problem with the BallLeft skin. When the border already has another skin and you try to select BallLeft then its already highlighted so you can't click it and it won't change the skin. The workaround is to first click another skin and then click BallLeft and it changes. And it works when you select BallLeft the first time (when the border is default). But this could cause some confusion.
