The <title> tag does it with no big issue. Though an external <link>ed file (à la RSS/ATOM) would be much better. Meta tags are not really structured and forces everybody to download a bunch of browser-specific crap they don't carte for.

Why not? If you don't already have a menu with these "essential tasks" it becomes a great one, and if you do have one and don't want to bother with reimplementing it as <menu> (yet anyway) display: none on the jumplist menu.
