FrameTitle is the Zope product for all of us who like to work in several browser windows or (for browsers which support such a thing) tabs, and who dislike the fact that the window or tab titles don't tell them more than "Zope on localhost:8080". FrameTitle overwrites the manage_page_header with a version which, at every call of a management page, overwrites the title of the top frame, yielding a much more informative visible title.
