People that stacked Scrivener
I've recently started taking writing seriously, and was looking for something that works well with how I work. Scrivener is flexible, easy to use and its full screen focus mode is seriously a game changer for someone like me who's so damn easily distracted by Twitter...
The best tool for screenplays. The card view is fantastic - it allows you to move scenes around easily in a way that no other screenwriting program allows. That maps very well to what screenwriters do in real life with post-its - move scenes around and see how it reads.
Write/research/plan/organize anywhere on multiple platforms, but stay organized. No more lost notes, illegible writing. Even has a focus feature that blocks all the pings and pop-ups that sidetrack the easily distracted (like me!)
