The courses can be sorted by alphabetic order / modified date / created date.
Also you can filter the courses by a template.
As a course developer you can use the navigation bar to navigate through the courses and the course structure. From the navigation on the left you can open any course, section or question and edit it.
The navigation bar in the question editor gives a complete overview of your course structure when you are editing a question or a content item. You don’t have to close the editor to move to another course item.
