Why doesn't exist something like a [top]-button? I really miss that. If a page
is 'long', you've the table of contents to jump to a point on the page, but
nothing to jump back... So you must scroll back to top.
It would be nice if you could implement a [top] link next to each section
editing button. Perfect would be, if you can choose via user preference if you
want that link or not. So it's optional to have the button.
