Feature suggestion: Completed courses marked "complete," removed from "My Courses" list, etc

Hello! My suggestion is this:

Once you've successfully completed a course (whether that means completing every lesson and then taking the course challenge, just hitting a button that says "Complete," etc), the course is marked done in some way, gets automatically removed from your "My Courses" list, and maybe gets added to a new list called "Completed Courses" or something like that.
