One quick plugin (that I just created) (download the plugin here) to add a “Hop To…” dropdown to your new WP Admin Bar, which gets filled with a list of all your site’s Pages, Menus, and (Post) Categories. So wherever you are, you can jump to any Page / Category of your site, with 1 quick click. Pretty slick?
Update: the Admin Bar Hopper plugin is now hosted in WordPress’s Plugin Repository! Check it out on WordPress.org.
A good plug-ins, but should reduce the speed of web pages
