I visited yesterday with the writer Cait London, a novelist with dozens of books in print, and she told me that one of the most valuable computer tools she'd found recently was PageFour -- "a good place to stash story ideas and develop them," she said.
"The sample is great to try," she told me. "I got it and a few other helper programs at bitsdujour.com and watch for the discount programs to be the special of the day. It saves in .rtf which is great, also Dragon works with it."
PageFour - Outliner and Tabbed Word Processor for Writers
PageFour is a tabbed word processor and outliner for creative writers. Where other word processors were designed with the business user in mind, PageFour aims to meet the needs of a different class of writer. It does not improve your prose or make you a better writer - only you can do that, but PageFour does make your job just that little bit easier.
