I never did get to find out what it does, the web site isn't very specific and since it is geared up to use youtube to present what it does that is a dead loss for me.
I have used RocketDock for some time now and it really is basic and I have been looking for something a little more flexible and I have been considering StarDock's ObjectDock.
From what I did see of bump top, RocketDock is nothing like it.
