-No close/minimze: Really annoying, cause if you change your mind, you have to kill the process in the task manager.
-Hideous UI: Ew. Obviously, graphics was not the creator's strongpoint.
That's about all. One other nice feature that I haven't used is cloning. According to the author, cloning a drive means that after the process, you should have two identical drives, and you can switch out the old for the new and the comp should run the exact same. So I guess that cloning would copy the MBR and everything, but I haven't tested it.
