The currencies I'm after that I couldn't find in there were (I went to http://www.exchange-rates.org and had to dig a little more to find them too): - KHR (Cambodian Riel) - LAK (Laos Kip) - VND (Vietnam Dong) I guess the ability to add and edit your own currency rate would be handy if you are in a country with limited or no internet available (for example ^^^^^) and couldn't get online to get the exchange rate(s). I do like how your application gets the exchange rates online
