I also have a suggestion for the transactions tab in the payment section. As an example, say a contact has three transactions. At a glance they all look identical, but they aren't. One might be an opt-in and the other two upsells, and there's no way to tell them apart without opening each one.
Would it be possible for the dev team to display the order name directly in the transactions tab? That way we could tell exactly what someone purchased just by searching the names, instead of clicking into each transaction one by one to find out. Having the order name visible right in the tab would let us differentiate purchases at a glance.
