Wow, no replys. I have not found much, for a directory of classes you may want to look into a web page, the raspberry pi can host a local web server and display what you want… (I used https://www.w3schools.com/html/html_basic.asp to help set up the page). Then you can just display the page or put the page in your MM with iframe.

Or some kind of note module like Wunderlist, that way it will display classes, and you can change them on your phone/pc.
