Bah! Can't believe I missed this article! However, I was having difficulty finding the time for Steemit when you posted it.
I am loving yWriter. It hits everything for me and you wrote a great, comprehensive review here. I'm also enjoying the organization for all that stuff that isn't novel: character backgrounds and notes, world building stuff, significant items--there's a place to organize all of that. I particularly like the "Project Notes" tab for a lot of world building stuff, because you can have it all broken into separate articles that are listed under the tab.
I'm glad to see you're enjoying the software. It's great, especially considering it's free. I even modified my windows theme so I can write on a dark background, since that's where yWriter pulls its display settings.
I like it a lot too. I may yet switch to scriv if they ever offer a good android app, but pretty happy with Y for now. ;-)
