I've often had the same experience, people's workflows are pretty ingrained (in general, not just screenwriters). But I've done some pitches where a writer had a lightbulb moment, and realized that collab and versioning really would make things easier.

I put great emphasis on the app behaving similar to current screenwriting tools, and the collaboration/versioning features just being there when they are needed, so the change in somebody's workflow can happen gradually.

I'm curious which approach you had considered. And would love to get feedback from writers/filmmakers of all backgrounds: m@arcstudiopro.com
