Navigating the MarkUs Dashboard when there are a lot of courses (which can be common, especially for a larger, shared MarkUs instance) is a bit difficult (and when multiple instances of a course are on the dashboard, it can get fairly confusing.)
It would be nice to have some way of reorganizing the courses in some way (e.g. to hide some instances, reorder them manually, or just to have a category for 'favourites' and the ability to favourite/unfavourite a course.)
