When the join slide/codes are up, it's hard to tell how many students have actually joined. The number of students who have joined (and its growth rate) is a good indicator of if students have had enough time to scan the QR code and log in etc., or not. While the "users" window can show this, it also shows all the names and email addresses, which is less than ideal. Please add the number of students who have joined to the join slides and the join code windows.
