Hey. We could do this before but after some update it’s impossible to edit players names and ranks in the demo board.
It’s a useful feature. When you want to make a relay it’s nice to make a demo board before the game started (and before you know players colors) and swap the player names if you didn’t guess colors correctly.
Also sometimes you make a mistake in a name or rank.
From the user’s point of view there’s no reason to prohibit name editing.
