Update 2006-05-19: Now with collapsible menus, which remember their position. If you're using Greasemonkey, please reinstall the script above to get it working properly.
Update 2006-05-30: I updated the links to point to the latest and greatest versions. The Greasemonkey script doesn't reflect the final design, but still works.
