Adds a tab to the WP Admin Bar, to Hop To the various parts of your site, so admins have any Page / Category of the site just 1 quick hop away.
Admin Bar Hopper currently supports listing:
All the first level links ("Pages 1-10", "Menus", "Categories") go to the appropriate Pages / Menus / Categories area on the Admin side. After that, all direct links to specific Pages / Categories will take you to the front-end view (what visitors see). You can use the separate "Edit Page/Post" link in the Admin Bar to Edit that particular content.
A Settings page gives you three checkboxes to control which of these groups of links to add to the Admin Bar.
Not at the this time, but future releases will add support for these other areas of WordPress.
