at my university, we have a faculty lead model. the lead faculty creates the course in canvas and adds the teaching faculty members to the course so they can import the content into their section. once a semester, a teaching faculty member will import their blank course into my fully developed course, resulting in the loss of all of my work! The ability to create a "course restore point" or something like that would be wonderful to have access to so instructors can simply restore a previous version of the course from a restore point. Even easier would be to have people roles that don't allow for importing into the course.
