I recently read a book where each scene began with a word in all CAPS, and I thought this was the clearest and most obvious scene break tecnique I’d seen to date. I’d love to see this as a feature in an upcoming release.
The only way to do it now, is to put each scene in its own folder, and make a page break between each scene - then you can select CAPS for the first page. Obviously, this would be ugly, and wasteful in a paperback book.
