This does look good, and answers some (just some) of my other concerns over on the other thread.
For the “in limbo” amount, I’d be concerned I’d spend it before it was claimed. How about creating a Pot on–the–fly for Pay Anyone links and deduct the amount from my balance, placing it into this Pot? You could also show it in Committed Spending. Then when it’s claimed, and if there are no more links in circulation, just delete the Pot.
