I would like Opera to add new unit for Nepalese currency (NPR). Considering there is already feature to convert to Indian Currency (INR) adding Nepalese Currency (NPR) would be straight forward by multiplying Converted INR by 1.6;
E.g.: $ 1 USD = Rs. 75.93 INR
Rs. 75.93 INR = (75.93 x 1.6) = Rs. 121.54 NPR
