Sound notification with improved accurancy - rings no later than at mode select.
Well-developed sound notification control panel with ability to save settings using cookies.
Function to look up games in progress.
CAUTION: From time to time sound notification may ring when game didn't start. It happens because bots update their status only every 5 seconds (based on my observation) and sometimes in addition their response may get delayed, so script will still think that lobby is full, despite the fact it isn't.
