Sounds

And for those who would find the sounds annoying their should be an option to turn them off

Nice idea mokona! I second the motion. Having an audible alert (user customizable) for countdown timer would be excellent. It would allow you a couple seconds to get out of chat and into command. Some might argue, "well, if it's a problem, just set the timer on your phone!" Good idea, but it's only able to be set in 1 minute increments... So I round down, and then have to stare at the screen for up to a minute after the alarm has gone off before I can press command. I've actually become entranced at times while watching the counter drop and just continued to stare after it hit 0:00!

I agree that option is definitely needed if sounds are introduced
