My friends and I have all experienced closing the browser and finding no savings. Especially for freshmen, they may not know they need to save when they first use this tool. So, I think adding an autosave feature will improve usability.
The creation or login UserID is displayed if the user does not automatically log in to the previous UserId when adding a course.
Autosave can call every minute, or every time after adding, deleting, or making any changes (but this may give the server a lot of pressure?).
