Right now, it is not possible to deactivate (and after that, activate) an entire course at once. That is usefull if you use a course for extra work for students and you only want them to have access to the course during school hours.

It would be nice to have a deletion button in the list of courses/projects to make end of year clean-up easier. It's use could be restricted to ONLY the person who created the course/project.

Schools often use courses as communities, libraries and the like. And as members of a teachers' community all teachers are given the teacher role.
Unfortunately this means, that all members have the right to delete and to archive the course.

As some of these communities/libraries have maybe 100 members, there is a good risk that some of them one day would feel like deleting or archiving the course.

To prevent that it would be nice, if a course administrator could give only some of the teachers - or none of them - the permission to archive or delete the course.
