The mapping part of Novamind has gotten fast, solid and very usable over the last few upgrades. It's the best mindmapper on the Mac. And i was very excited to see the addition of the screenwriting module, which on first viewing looks like a lean clean straightforward and visually pleasing cocoa alternative to Final Draft et al. Unfortunately, like "outline" view, screenwriting view is very limited and rigid. It's ok if you write EXACTLY as expected, but the minute you want to go back and edit, use Caps in an unusual spot, change the assigned style of a paragraph, or move things around, things can get buggy and confused very fast. And Undo refuses to fix things.
It's a shame, but I certainly wont be giving them any extra money for the module. At least until version 2.0, hopefully fixes these problems in mid april.
