A mirror user element can be used to duplicate a video stream from another user element. It can be used to achieve an effect like this:
To make a mirror user element, insert a new user slot into your canvas. In the Advanced Properties panel under the Advanced category, click the next to "Mirror User Element. Use the dialog to choose another user slot in the room or workspace. Your element will now "mirror" whatever is shown in the chosen slot.
Note: a mirrored user slot is not a normal "joinable" slot, meaning you cannot drag-and-drop someone into this slot (you must drag-and-drop into the original slot that this one is mirroring).
Mirroring into Other Rooms
You can mirror elements that are in a different room, too. Just keep in mind that the person who is being mirrored will not automatically know that people in another room can see/hear them without being told.
Mirror elements may soon be deprecated in favor of a special mirror mode on the element. They will still be supported however.
