Here's a new tool for scriptwriters called 'Amazon Storybuilder'. It's a free app that works on your computer or mobile device. Storybuilder emulates the oldschool 'Note cards on a corkboard' used by countless scriptwriters and directors to quickly organize, reorganize or edit elements of a script. I've never used note cards, but I understand the value of them.

The app is still in Beta and it's (yuck) cloud-based only. However, you can fit up to 1,000 cards per board and adding a new board is no biggie. Amazon claims no ownership on your project unless you go through their 'Development Setup' whereby you pitch a project to them. For free and being able to see your project whether on your desktop, laptop or mobile device it's definitely worth a look....
