#WritersCoffeeClub 1/4: Share a tool of your trade.

For writing books, it's @scrivenerapp —been using it since 2008 (it was still in beta at the time!) and have written about 25 books using it in that time. Many of which would have been impossible to produce without it. It's not a word processor (although it subsumes one), it's a tool for managing the deep structure of book-length compound text documents. Makes complexity transparent.
