Well I heard I can make character sheets and an outline all on Scrivener.
I've been using Final Draft 8 to write so far and now I'm halfway through my script I'm tempted to check out Scrivener and move all my character sheets and back story there.

Has anyone used it for scriptwriting? How can I import my Final Draft files there? Or should I stick to Final Draft and my Word documents containing everything else? (is there a way to have character sheets and such on Final Draft that I have yet to discover?)
