Scrivener

After hearing everybody rave about it, and knowing I would be losing PageFour with the switch to the Mac, I went and got Scrivener yesterday. It's installed and registered, but I haven't played with it yet. I have two projects that are very time-sensitive to get done, and I don't want to waste time I don't really have getting comfortable with a new program. But as soon as they are done, I'll be all over it.

In the meantime, I'm curious what others like most and least about it. If you have Scrivener, share your favorite tools, most hated aspects, or any advice you might have. I'd love to hear it.
