I am sorry for this super late response, I was super occupied with some unexpected but very nice things, but I didn't forget that I have comments here to respond to. Especially as I like the story of the jar and $5 every time the wife finds something. That is cool, I think we (mothers, wives) would be super rich if we would implement this :D
Oh, and putting a label on the cable is a great idea too. Why we didn't think about it earlier? :)
