Please add the ability to spectate people on our friends lists. The way it should work is that I should be able to click on my friend on the friends list, and there should be an option called "spectate game". Even if the friend were to /hub the one spectating will still be able to spectate the game.
I think it would be an amazing feature to have because then cinematics for content creation would be made a lot easier. And I would be able to watch people do duels against each other, watch them finish their eggwars mega games, and also their skywars games while I wait for them.
