I agree. The global nav should not just disappear when scrolling down the page, I prefer that when it scrolls down, it inverts. That way I don't have to scroll all the way up to the top just to see the search box/profile dropdown. Whoever is coming up with these totally lame ideas seems to have missed some crucial lessons in UX.
