This plugin adds an auto-hide feature to the WordPress Admin Bar or Toolbar.
Since WordPress 3.3 the Admin Bar is called Toolbar, but this plugin will keep its name. This plugin makes the Toolbar disappear. When hovering over the top of the site, the Toolbar is magically returned. You end up with more screen real estate and the added functionality of the WordPress Toolbar.
