Quicksets

Quickly set course and grades visibility, number of visible sections and “Edit sections” — insert, delete, reorder, rename any course sections from one screen.
The “Course settings” block (heretofore named, “Quickset”) has changed dramatically.
NOTES:
“Update settings” is the default focus button so <ENTER> will cause that button to be submitted with any changes to:

Grades visible?
Visible sections

Studying this screen you will discover it does everything it appears to do:
Delete course sections from anywhere in the sequence (if resources exist in that section they will be moved to the “Zero” section — a warning pops-up to remind you)

Quickly reorder sections with no clicks and no reliance on how AJAX is feeling today.
Edit the names for any of the sections which is particularly handy when first setting up a course (think of the “click savings”
