Include more information to the class calendar

Currently, the class calendar only shows the time and name. It would be really, really helpful for admin staff to easily see more information without having to leave the page.

Information that would be great to see would be:

Teacher name

Student names

Attendance history

Attached is an example of what I mean from our previous software. The list of names on the right-hand side is from the highlighted class. Also, when you hover over a class, the list of names plus the teacher's name show up in a pop-up box.

It's all very neat and allows admin to monitor class attendance throughout the week from one page.
