I gave it a try a few weeks ago.
Very promising, but the version I used was
extremely buggy. Got a few sample chapters in before it screwed up royally when I began moving things around and basically stopped working.
If they ever get the kinks worked out I think I'd be willing to buy a copy. It's pretty good about staying out of your way. And very intuitive. Of all the novel "organizers" out there, this one seems to have the smoothest workflow.
I'm gonna keep an eye on this one.
Note: You can get very similar functionality (plus some extra features) with a free open source app called
Storybook available
here.
