This latest version of StoryBox has a huge number of fixes, improvements and features included. The biggest feature/change is “real” support for multiple stories in the same project. Before, you could create additional stories, but you couldn’t keep track of their word counts separately, and exporting the one you wanted was confusing. Now, you can track wordcounts separately for each story as well as continue to view the overall word count of the project. When you use the File->Export menu, you now get a list of all the stories to select from.
