I just bought it over the weekend, so I haven't really learned my way around it fluently yet. I will say that it seems to be an INCREDIBLE program, putting a lot of power at your fingertips in a fast and easy way. I do find the documentation to be pretty sparse (if you have read the Zenware site, you have seen all the documentation, from what I can tell), but maybe this will change as people write tutorials or what-not. In any case, if you are creating characters or textures, IMHO I would pretty much say this is a must-have.
