Comment on OmniOutliner

It took me a while to get used to the program (it came free with my PowerBook), but now I use it for just about everything... taking notes in class, to-do lists (or any kind of lists, for that matter), simple databases... its just amazing. The program is very feature rich and still easy to use at the same time. There are one or two features that I think are missing, though (that's probably why they have a more expensive 'professional' version, but I'm too cheap to upgrade :-P).
