The status bar at the right of the menu bar reports your live session: an active call, who is online from your notify list, how fast the server is answering, and whether sounds are muted.
Your nickname, your identity state and the conversation you are reading are not repeated here — the chat window's title bar names them.
Two Sections
Left:
Active group call or P2P session, and the online buddy badge.
Right:
Lag indicator, local clock, and mute toggle.
