If you want to see what your collaborators are doing as it happens, click the gear icon at the upper right, and on the menu that appears, turn on the Collaborative cursors switch. Then you’ll see what other people do on the whiteboard in real time, and they will see your actions on it, too. Each person’s cursor will have a unique color and will be tagged with the person’s name.
