I work on a number of committees and standards bodies that could really benefit from Vyew. But one thing we need is a speakers’ queue: a way for participants to request to speak, and for moderators to recognize them in the right order. You could use chat to do this, but then you’d be forever scrolling through to see what’s up.
You could use another button like the beep button down below the chat window. It makes a sound and also puts “ATTENTION” in the chat window. How about something like that that put an icon next to your name in the participant list, with a number indicating the queue?
