I wouldn't trust this too much (on Qiana Cinnamon). Some of the entries it wanted to remove, I was pretty sure should stay in. So I exited, and got a very strange looking dialog, asking me (as far as I could decipher) to reconsider my actions. Thus I did - or rather... I gazed at it for few seconds, trying to figure which button meant "get me the h*** out of here!" ;) In short: This does not seem like a finished program.
