Why have a desktop per page? One desk top for all the pages, like Illustrator and old Freehand.
Work with all content on pages seemlessly, align, group, colour etc. Currently clunky and annoying having to select view type in the pages menu, even with the keep object on desktop.
Marque select objects etc across multiple pages etc.
Think of it like having all your pages on one desk, not each page on a separate desk.
