The six primary tabs for a course in Notebowl are Bulletin, Roster, Documents, Assignments, Grades and About. These can be customized to suit the course language, as well as disabled for specific user roles. There is also a More tab that provides options not available for students.
Inside of a course, click the More tab, then click Tab Settings to open the Tab Visibility window.
Here you can enter a custom title for each tab that you wish to rename. You can also uncheck any boxes in a tab row to hide it for a specific user role (Instructors, TAs, Students, or Observers). Please note that the Bulletin tab cannot be hidden.
