How about a "Ding" when query execution is complete?

Very often I run a query and go to other applications (like Facebook :) ) while waiting for it to end.

But to the only option to know if it is complete is to go back to SQLnav (Alt+Tab for win). And often when I remember to go back it has already been a while since the query already has finished. So again - the precious time is being wasted :)

It would be great if SQLnav made some kind of sound would when the query (or script) is complete.

Even better - if there would be a setting in preferences - to turn on/off this sound and maybe an option to choose from various sounds (maybe even choose my own sound file :))
