Get a distractionless wp
I recall once seeing a review of some "distractionless" word processors. The idea is that the word processor offers just one text window with minimal decorations and other distractions, meant for writers that want to fully concentrate on the text.
Too bad I cannot right now remember where I saw it. (Thought it was lwn.net but nothing turned up when searching there).
None of them were household names, which is not surprising since their users are a rather specialized group. I think the idea has merit.
