Two things I really miss compared to meatspace for zoom (thinking both about social gatherings and meetings):
1) the ability to direct-channel voice call someone in the room. Can mute (or dim) the rest of the conversation that is happening, but allow for focused discussion aside. This would be a huge advantage over actual meetings where we must use furtive whispering. Obviously not great for small meetings (distraction maybe) but excellent for large ones and really excellent for social gatherings.
2) when using breakout rooms, the ability to still see what is happening in the other breakout rooms. Just like when we are separated in groups in a physical room and we can still peek over at what may be happening in a different group (in case we may want to bounce to a new conversation).
