I'd like to see a tool like this, that could be used to adjust books to movie script format. When scenes are taken off a book, sometimes the implications and ramifications of that scene aren't taken care of, leaving holes in the script. For example, the Half-Blood Prince movie has a couple of moments in which, unless you've read the book beforehand, you're like "wtf are you talking about?"

Tool looks very cool and I really like idea behind it. I am not a writer, how is this useful to you who write longer prose?

My novelist friend behind this writes 700-900pp books and complains he has to switch between Word, Project and Excel to keep everything straight. They're hoping it's useful for complex universes, fan fic and investigative journalism too.
