There is a color square in the bottom right corner of Video & Voice icon for each player. I noticed that this color is selectable if you click it, and it crops up as a color when a ruler is called up and in the outline of dice when a die-roll is made in the chat box. That is useful to tell which player is doing those actions. But I think the color-square feature should be extended everywhere. Sometimes I can't keep it straight which character name goes with which player. It was suggested to me that players can put both their character name and player name (in brackets) on the icon. But it would help if that color box is incorporated, say, in the corner of a token controlled by the player, and in the chat-lines whether the player is typing as their name or their in-character name.
