Are there any apps marketed towards fiction writers and/or screenwriters that are also accessible?
I would love an accessible version of Final Draft and an iOS version of an application I used years ago to keep track of notes, character information and other such things called Treepad. It used a collapseable tree structure to allow nested subdocuments so I could keep whole project notes in the main tree and then notes and other subdocuments pertaining to particular chapters or sections in the branch for the section in question. There might have been more efficient ways to keep track of things, but not in any accessible application that existed at the time. It would be great to have something like that available on iOS devices, particularly if there was an equivalent app for Windows and Mac that could then sync with any devices being used by the writer.
At any rate, I do not have a lot of hope on this topic, such apps would be a very narrow niche, but one can always hope.
