Moving between a course and its classes is now easier in the admin.
- Editing a class that belongs to a course shows the course name in the breadcrumb trail at the top of the page, and it links back to that course's scheduled classes.
- Classes that are not part of a course keep the trail they had before.
- The scheduled classes list now has an Edit class option in the row menu, so you no longer have to click the row itself to open a class.
- If opening a class does not complete, the list no longer stays stuck and you can try again straight away.
