If I am using the same machine for Multimedia as receiving mail, on the fly, then the alert sounds that I have set for various filters interfere with the enjoyment of the media. OTOH I do want these audible alerts, most of the time. I would like to see a way to mute all sound from The Bat, on a temporary basis, say, from a menu item on the tray icon. This would be a great feature and really easy to build in. I, personally would appreciate it a great deal, since, when playing multimedia, all my sound is redirected to my stereo system and amplified considerably.
