* When I tell it to go fullscreen, it adds a second, autohiding toolbar, but keeps the toolbar that was already there. So 2 toolbars I don't want, both nearly the same. Probably because I'm not using gnome shell, but sheesh.
* A few seconds after scrolling, it auto-hides the scroll indicator. Because who cares where they are in a multi-hundred page document? (Oh well, at least the page info is displayed on both toolbars..)
For what it's worth, when I toggle full-screen in Evince running under Metacity, I only get the auto-hiding toolbar, so it's not specifically a gnome-shell thing.
