Something that would improve usability is to add keep editing mode when adding/updating a page.
I.e. [Add and Keep Editing Page] button.
When working on the web, I always have the fear of having my browser crashing. Using such a feature (in combination with a publish/draft feature) might be interesting. I could save at anytime, without fearing losing all my work.
workaround: If you hit Preview a draft is saved automatically.
