I have ObjectDock Plus, and it works fairly well. There are just a couple of annoying issues.
Firstly, it seems to randomly shut down for no reason at all. It just disappears with no error message. All I have to do to get it working again is reload it, and it loads up fine. It's just very annoying to have to do this. It happens 2 or 3 times a day.
Secondly, sometimes the way the icons respond to being clicked changes. Instead of loading up the program, eather nothing happens, or a right click is simulated instead of a left click. Again, the problem is fixed by closing and restarting OD, but it's just annoying.
Other than that, everything else seems good.
Cheers
