oh, that's kind of clever. So when not otherwise in a zoom, each of you hang out in your own breakout room so others can "drop in"?

Exactly. If I want to drop in all I need to do is to check the breakout rooms list then move to the room where my colleague is. And once done I can go back to my breakout room. We also use it when pair programming remotely. It's quite effective and it eliminates communication barrier.

Very cool. Thanks for the reply.
