Thank you for adding the BetterBags compatibility option, however, while the functionality from Peddler works, but the coin icon doesn't show in the bag.

BetterBags:

As a note, at this point I'm not sure this works at all with BetterBags. It hasn't been for me. I'm not sure if it's just that I can't tell if something has been tagged, or if it's not tagging at all while using it.
