Feedback or visual indicator for players left from the lobby/game

I am suggesting adding a feedback or visual indicator to the scoreboard after the game to show players who no longer are in the lobby.
Either of a chat message by system: Player has left the lobby
or make make a visual indicator to show that the player has left. Ex. making the name color dimmer or add a small icon next to players name to show that he is no longer in the lobby.
As sometimes players stay to chat a while after the game or even spectate the game if it is still going on and this maybe just me but i feel like this is minor information that is still needed. As a i sometimes stay chatting and i might wait for a while for a reply, but not knowing if the player is still there because there is no indication if he/she has left or is still there.
