I'm a designer. I have a ton of courses in my "all courses" list, and would like to periodically switch which ones I'm able to quickly access from my customized list, even if the course is one from the past. Canvas says "To customize the list of courses, click on the "All Courses" link and star the courses to display." Of course they fail to tell you that this doesn't apply to past enrollments. Bummer.
My idea: Make it so when I click on the star next to a course in the Past Enrollments section, I don't get a message that says "This course cannot be added to the courses menu at this time."
