I had to be as honest as David-- there's no changes that really help. Even though the editing menu is sticky when you scroll down, I discovered that it doesn't work. For example, if I am trying to format a header, if I am scrolled too far down, clicking on it won't show any drop down menu. I still have to scroll all the way up for it to release a drop down menu. ANNOYING. So, I re-installed to the previous Wordpress until they work out all the kinks.
