When I edit a page, more than once, I want to edit the next page as well. Now I have to go back to 'view all pages' and select the next page there. (Don't forget to save the changes first!). So this is about 4 clicks (save, all pages, next page, edit).
I suggest a 'save & next' button on the page, when you are editing it, and a 'next' button when you are just viewing the page.
