Navigation Bar Tabs
Administrators can customize the navigation bar tabs for the entire site or groups of users via user roles.
The tabs can be reordered, enabled or disabled, and renamed.
The tabs that are available globally are set on the Admin > Top Level Navigation Bar/Search page. Drag and drop a tab to reorder it or move it into Enabled or Disabled.
