We really need to add "Issuing Entity" to the banknote section. This will allow us to differentiate between issues from different banks (crucial for modern issues from Scotland, Northern Ireland, Hong Kong , Macao and India) as well as earlier issues from nearly every country in the world before national banks gained a monopoly on paper money production.
Just consider how difficult it will be to navigate Scottish banknotes if we can't easily separate the different banks:
Clydesdale Bank
Clydesdale and North of Scotland Bank
North of Scotland Bank
Bank of Scotland
British Linen Bank
Union Bank of Scotland
Royal Bank of Scotland
National Commercial Bank of Scotland
National Bank of Scotland
Commercial Bank of Scotland
These are just those in operation since WWII!
