I know I have to be prejudiced, but goodness, I think it's seamless. I think I really caught the voice, and my wife claims the same thing. Now I'm waiting to see if a couple of friends who have also read the original give me the same report.
I did catch a very few more things this time through, but mostly wording adjustments. If I read it ten more times in a row, I'd fiddle with wording every time, so there isn't much point to that. I did catch a couple of minor continuity gripes fans of the original might have, and fixed those. They weren't continuity problems within my own novel, but connections between mine and the original book. The people I have a version out to are reading both novels in sequence also, and have a version prior to today's changes. I'll be interested to see if any of them notice those details.
Scrivener vs yWriter
I did finally get some time in on the Scrivener tutorial. The main comparison for me will be which one best helps me organize the stories, action, sequencing, and fates of the 46 characters in my upcoming project, and I haven't progressed enough in the tutorial to begin to see how Scrivener will contribute there.
However, I did run into one huge advantage for the software: Typewriter Mode. When you take it full screen, your typing stays on the middle of the page and everything scrolls up a line as you go to the next line. Those of us familiar with Word are well aware of how we run into the bottom of the page, and have to scroll the page up so we aren't scraping the bottom of the window, sometimes with our line of text cut off a bit at the bottom.
That's a bingo feature to me. If I find out I'm at least as happy with how I can define and organize characters, that makes the sale.
