When working with a group of students it's chaotic to give 1 on 1 instructions or form teams because everyone is able to listen to each other, regardless of their position on the map (playground).
It would be great to only see and hear students whose avatars are close to mine. Similar to Gather, WorkAdventure, MozillaHubs, etc.
Honestly Koala is far better than any of those, but we're stuck with the alternatives when working with groups of students.
