I've read various posts here and it seems one cannot unpublish a course.  This is not about student access to it, I know how to fix that, its about the very cluttered interface when there are dozens of "published" course in your dashboard.   I have 75 courses in my list and I like to keep archived ones for comparison to what I did before, but its too messy to have them all in published.   

I cannot understand the rationale for not allowing unpublishing. Once students lost access it is effectively unpublished to them, so why make it stay published and mess with the UI?
