first of all congrats, I love Mondo and I use it all the time.
My idea is about providing more granular transactional data and rather than stopping at “merchant” level, actually returning product information/ SKU level so that if I spend online, I’m able to see how much I have spent for every product, category, brand.
merchant = “amazon”,
category = “Book”,
SKU = 0517599805,
Title: “History of Money: From Sandstone to Cyberspace”
Is this something you are considering?
