- @mention: typing @username in a message sends bell char to that user and highlights the message content in bold yellow for them - Idle timeout: disconnect inactive clients after TNT_IDLE_TIMEOUT seconds (default 1800 = 30min, 0 to disable) - :list now shows connection duration per user (e.g. "alice (12m)") - Document all three features in help text, manpage, and README Closes #46
