"Lower all" hands button.
Students forget to lower their hand. Teachers need to be able to lower all hands.

We use the raise hands feature during training sessions to keep attendees engaged. It would be very helpful if both a meeting organizer and meeting presenter could lower all hands after asking a question or poll.
This. 1000 times, this.
I use the hand-raising feature a lot. A lot of them forget to lower them in general, too.
I can lower them individually, but that would be very slow when I've asked a question to which 20 students have responded.
