It would be amazing to have a pop-out option for the video chat - facilitating separate windows for role play/player interaction and the map would really make a difference for players with a two-monitor-setup. That way, the players videos could fill a whole screen, you'd be able to really see the other players and still see and access the whole map without the player icons hanging around and in the way, wherever you place them. Having this option would make it possible to customize the roll20 experience to your setup (and still have it the old way if you only have one monitor).
