My real pet pieve is this:
Spell checking invokes to early. It should invoke when you press space, or return, not when your still on the word. Otherwise it marks it as an error until you complete. That flashing red line is just plain annoying. An option to delay it until you ‘leave the word’, or better yet ,make that the default, would be greatly preferred.
Daniel did a list documenting the new features, so no need to re-write that. All around a great build. All html geeks, and non-geeks should be checking it out. Makes web development easy.
