I would find it wonderful, if we could have an integrated video chat in Tabletop Simulator.
Yes, you can just use zoom, jitsi, skype, teams or whatever in parallel, but most of us do not have a second screen so you can’t see all of your friends at once.
If you want to go the extra mile, replace the floating profile picture with the streem from that players webcam. That way, you’re REALLY sitting at the same table as your friends.
