Built-in chat

Opens each service's chat inside GameHub, in a panel you can resize to whatever width you like or pop out into its own window. Each service turns on and off separately, with its own sound, and with TeamSpeak you see who's talking in your channel.

On top of that, while a game is open your Discord status shows what you're playing (“Playing CS2 on Arlequin GameHub”) and for how long (you can turn it off in Options → When playing).

While you play, the chat can stay connected even when GameHub closes its window to leave everything to the game: you choose it in Options → When playing.
