I often have to run scripts that take a lengthy amount of time (between 3 and 30 minutes, and it's not known ahead of time exactly how long it'll take). Currently I have to remember to keep checking back to see if it's finished yet as I switch over to another app to work on something else.

It would be much more useful to switch that 'polling' to 'interrupt-driven'. :) Specifically, I'd love to be able to set an option similar to "if a query runs longer than X seconds (X = 30 would be what I set it for, but I could see others wanting different values), then do something (flash the window like IM apps seem to do, play a sound, whatever) to signal to me that it's done"
