The Admin Toolbar was added to core in Drupal 7. In earlier versions of Drupal, there were several modules that added similar administrative interfaces including the Admin Menu and Admin module. While those modules are also available for Drupal 7, some of the advantages of using the core Admin Toolbar are:
- Well Supported. Because it's part of core it is more likely to play nicely with other modules like CiviCRM.
- Your site matches screenshots and documentation on Drupal.org.
- It provides a visual separation of staff navigation from producer, self service navigation.
The Shortcut bar is the lighter grey toolbar immediately underneath the Admin Toolbar.
Customizing the Admin Toolbar
The first reason to Customize the Admin Toolbar is usability. If you try to add every possible option at the highest level the Admin Toolbar ends up wrapping and isn't covered by CiviCRM's admin options. If you leave a link to the Admin menu itself
http://yoursite.com/admin in the Admin toolbar, al the shortcuts wil just be one click away.
The logic is to move items that most staff users never see down to Shortcuts and reorder the other menus into the most logical order.Read more
