It would be great to see exactly where the page breaks into the next in the script view.
When trying to make a punch/impactful page one, it would be really helpful to see what fits exactly on that page. Or on any other page if you want to keep the reader interested, to turn to the next page.
Also, I would love to see the return of the readability Display - that disappeared a while ago.
It could be an option to show or hide it.
