This screen is just for you, open it on your laptop or a spare Chromebook to moderate entries and approve previews without showing the class. Tap 💻 Teacher controls on a second device on the host screen to see the PIN.
Starts for everyone, same as the button on the projector.
Only you can see these. Hide anything that shouldn't reach the class, hidden entries are skipped by the AI and the reveal.
Tap any item to check or un-check it for that group, handy when a group forgets to tap.
