Scrivener I may turn to; I've been using other tools for screenplays. Let's see if my serial number from 2007 works... Novamind looks intriguing and probably more in line with the structure. Thanks for that. LA minimeet. If I'm there, let's do it.
You could go with Final Draft, Complexity, but the entirety of Hubskina was written in Scrivener so I think we have a clear winner here. If you're looking for free, Adobe Story and Celtx both are. I wanted to try Final Draft but the price tag made my wallet cry in pain and hide behind my computer monitor in fear of use.
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...
