The idea is to make it possible to activate/deactivate an element for the same time span every day (or week) during several days (or weeks, or months).

For example: I want an element to be active during 2 weeks and only during my lessons on Tuesdays from 9:00 to 10:00 and on Fridays from 12:00 to 13:00. Right now, I have to activate/deactivate the element every single lesson again. It would be perfect if I could set a time span, and that automatically the element is activated during my lessons.

Right now, it is not possible to deactivate (and after that, activate) an entire course at once. That is usefull if you use a course for extra work for students and you only want them to have access to the course during school hours.

If pupils take a time limited test online they have the possibility to cancel the test and return again later on.
In other words they have the possiblity of finding answers on the net or elsewhere and return to the test.
Suggestion:  a possiblity of deactivating the cancel-button.
It's important for many teachers.
