Accessories-Command Window

In 3.0 there is a Folder called Vantage Basic with a menu option called
Command Window. We have been Live for 1 ½ years and no one here has used it
including myself.

I'm curious if and how others are using Command Window. Since we've never
used it I don't know if it is useless for most or if we are missing the boat
on some serious must-haves in this software.
