Change "available until" date when assignment is dragged in the calendar

    It is wonderful to be able to change the due date of an assignment by dragging it in the calendar. However, the "available until" date does not change along with the due date. This sometimes results in assignments being locked before they even open. It would be great if the "available until" date would change at the same time as the due date.
