More about video window placement. ( I mentioned this before, but in an incidental comment on a thread with a rather different main topic, where it will be lost. I am repeating the point here for convenience.)
I would like the video feeds to be arranged left to right on each players' window in order consistent with listing them in order clockwise around an imaginary table. For instance, if I were playing with Will, Nic, and Ed, and the video windows on my screen were ordered from left to right Agemegos, Will, Nic, Ed, then:
• Will ought to see Will, Nic, Ed, Agemegos
• Nic ought to see Nic, Ed, Agemegos, Will
• Ed ought to see Ed, Agemegos, Will, Nic.
Not only does this add consistency and verisimilitude, but in some RPGs (as in most card games) position at the table affects games play, with rules referencing "the player on your left", "the player on your right", and "nearest to the GM's left".
The GM ought to have control of different players' positions at the virtual table.
