If you are in a room with another person, you can have a short conversation with them in a different room. Our working title was "Stelldichein", but "One-To-One" sounds much better, we just didn't dare to use it, so now it's called "In neuen Raum" in German.
You can find the "In neuen Raum" function at the top right of each person's video, in the menu with the icon of a person, which could very well be a woman (you never know):
Once you have selected the menu command, the other person will receive a message and can choose whether to accept or decline. If they accept, both of you will end up in a new room. This will have an automatic room name such as "Chris & Anna". You will be out of the old room. After that, you can switch back to the old room using the room menu at the top left.
(We will expand this a bit to "popup rooms" that automatically disappear, and maybe it's better to show in the old room that you only exited and may come back.)
