This module adds an extendable command bar to the Drupal 8 administrative toolbar. The base functionality provides an ajax menu search autocomplete widget to quickly discover and jump to any page in the administrative menu, but it can be extended by other modules to add additional functionality such as searching users and content, or performing administrative actions like clearing the cache.
1. New users should be able to map existing knowledge to the Drupal 8 information architecture. These users may be coming from older versions of Drupal, or from other software. Being able to search not only the titles of menu items, but also the descriptions, allows for this mapping. For example, you can search for 'modules' and reveal the 'Extend' menu link.
2. Discovery of new pages is a challenge. Major improvements have been made to this in Drupal 8, but it's often still difficult to find a particular page, especially after installing a module. A menu search allows you rapidly discover what new pages might have been added and explore them. The default administration menu then gives you a solid 'you are here' marker when you get to any of those pages.
