Yeah, for screenwriting FD is my last resort for back and forth between me those who demand it; and after the feature free 'upgrade' pricing debacle and the hilariously awkward Scriptnotes episode with the FD guys who have now become a running gag between Craig and John, I'm pretty much done with it. Actually, since I found Fade In Pro I haven't looked back. Light, agile, modern and just gets out of the way for a draft. I think it lacks the annotated versioning/change tracking of FD but that's so much later in the development process (and such a specific type of studio writing) it doesn't really affect me at the moment. Celtx was always a nice idea but slow and unwieldy (cutting and pasting multi-page sequences into a 110 page doc was like waiting for the pitch drop experiment to happen). I didn't like having to be online to generate a paginated preview on their servers and the increasing move to cloud shenanigans was not for me. Never really played around with Story. I'm doing a lot of scratch drafts in Fountain, anyway, so I can use anything.
Fuck, dude, if I weren't under NDA I could tell you so many things about the features you were almost cursed with...
