I'm reviewing this again, and have changed a few things around. I came
up with a question, too :-)

Right now, if you turn off track activities, we put "<command string
not enabled>" in the query text. Shouldn't this also be a state, such
as "disabled"? It seems more consistent to me...

Sure, I was going the route of 'client_addr', i.e. leaving it null when not in use just to keep screen clutter down, but I'm not married to it.
