Oooh, the deductable tag is a really great idea. I will totally steal that for my YNAB habbits. It supports some coloring/flags you can set. I'm gonna go ahead later and define one for deductable. So smart! Thanks.
(I should also define one for money I expect to get back, actually. And another shade of this color for "debts collected". This way I can also see if anyone hasn't paid their debts yet.)
