The ability to create groups that can be synchronized with the class lists from Google Classroom and Microsoft Teams. It should be able to fetch a list of classes from them and to automatically (or manually) create corresponding groups. It should be able to synchronize the student lists automatically, or else manually with a button.
This would enable tracking and reporting on class students that could be used for school reports and tracking.
This is a feature lacking in Kahoot, Blooket, and other major competitors, and would be a MAJOR selling point to teachers and schools alike. It's sorely needed.
