For users with the admin role, submitted courses come with a notification that they can be approved by "adding to a cohort". I don't understand--aren't cohorts chosen by the instructor? Should there be an Approve button instead?
No, cohorts are not chosen by the instructor. Cohorts are added by admins, and adding a course to at least one cohort also doubles as approving it and making it available for enrollment.
Separating that out more cleanly would nice, but probably shouldn't be a high priority.
