This limitation prevents parents with multiple students from seeing all of their students coursework on one calendar. Currently, my students are enrolled in 14 different courses. Since the main calendar is limited to 10 courses, I have to individually look at the calendars of 4 of their courses to see what is going on, which is an inconvenience. It would be much better if I were able to view and access everything on the central calendar. It is too easy to miss important information when you are forced to look in multiple locations.
