sounds on new shouts?

If this is documented anywhere, I couldn't find it.

Many of my visitors have asked if it's possible to have an alert sound play when a new shout is added. I have looked, but didn't find that functionality. I can understand their concerns, as I keep the shout open in a background window/tab (depending on the browser I'm using) and it would sure be nice not to have to remember to switch back and forth when I'm involved in multiple projects.

Even just the ability to add my own sound file and have it play on each new shout would work.
