Switch between the teacher panel and the display mode of the loop

If you are in display mode of a started loop you click the small arrow next to the name of the loop to return to the teacher panel. Use the same arrow to switch back to display mode. That way, when you show your students the loop on a big screen,  you can avoid showing information about students that you don’t want other students to see. When you switch to the teacher panel you should disconnect the big screen.
