I like to keep my mIRC open all the time i'm at home, but it's often annoying when someone tries to reach me with 'important' news by messaging me or repeating my nick on a channel while i'm trying to watch a movie, for example.
So, i'm suggesting that you'd add a mute-button that would silence all sounds, beeps, flashes and whatever coming from mIRC. Maybe it could be used together with /away.
It would be like muting your cell phone

Keep up the good work with this cool piece of software!
