Currently the transactions list is confusing. The transaction is listed under the currency that was used to spend (source of funds). If you get a refund the transaction is move under the currency that it was on.
Exmaple: I had an USD transactions It was listed under EUR because it was paid using EUR. After refund it was moved under USD and I had to search for it.
Having multiple transactions list is confusing. I would like to have some filters if I really need to do this distinction. Generally I would like to see everything in one place.
