An ALL COURSES link should be added to the Dashboard. Either below the course cards, or in the right side navigation.
Students sometime call during the first days of the semester because they cannot find their current courses. I believe this happens for students who had Favorited courses to the Dashboard during the first week of their school year, but now those courses are unpublished and the new semester courses need to be Favorited. When they open the Dashboard, there are no Course Cards. Providing a link on the Dashboard to ALL COURSES makes sense. From a student point of view, they are seeing the courses they want to see first on the Dashboard with one click access to all their courses.
