I wish I could thank you more. I tried to have a look at the original source code and it was way beyond me

EDIT: Just managed to get to the extras-dev repo. Great looking app! Just a question, would it possible to include an option for someone to enter in their own currency manually and to manually edit the exchange rate? Also, sorting the currency by country would be an awesome addition too

You've done an amazing job! I'll be giving a real world test in a couple of weeks.
