Not sure if this is a bug, just a missing button, or not actually yet a feature!
Degree Audit Subgroups don't seem to be editable once they're created. For example, I've created a re-usuable group and duplicated it to make some small changes for a different Major Degree Track - the subgroups are all present, and I can add and remove courses, but I can't edit the group properties directly. This is important because that's where the 'Minimum Credits' option is located. So for the example in question, I need to take out two course (easy) and change the Minimum Credits from 80 to 50.
This would be a problem also if I'd made an error, or the required credit value changed - the only way to edit it would be to remove all the Courses, delete the Subgroup, and add a new one. It seems to be the same both for re-usable groups and non-reusable groups.
I may just be missing where the option is to edit it, but if not, some help would be appreciated - thanks!
EDIT: while I'm in the neighbourhood - it might be useful to have these values displayed on the main page for quick reference.
