Kevin and the guys and gals at Latte & Literature have finally announced Scrivener Three. It has only taken seven years. And it is not a subscription model. Unlike Ulysses writing app.
I have been looking at Ulysses as replacement for Scrivener for a long time but that became less pressing after the Scrivener for iOS was released.
There has been a constant stream on blog posts on their website. One of the post that really shows what they will bring to the table is the Linguistic Focus mode. This allows you to focus on different parts of the text, be it direct speech or adverbs, etc1.
When it comes out later this year I will totally be buying it2.
