Sorry but can you explain what is the purpose of showing the exchange rates inside admin?
Shouldn't we also show the exchange rate to the buyers before proceed to payment, using extra field at the bottom of the total price?

And also, paypal allows to receive in multiple currencies, can you enable the possibilities of allowing them to pay in their local currency?
I find it strange when i shop in my local currency, and suddenly on payment i'm asked to pay a different currency.
Plus, since we're talking about currencies, can you show them their local currency upon page load, by detecting their location using something like geoip from maxmind?
https://freegeoip.net/ is free.
