Add region selector to payment methods screen.
In the traditional currency accounts area, there are a lot of payment methods that do not apply depending on your region. As an example, I live in North America, but see a ton of payment methods with "india/". My thought would be to separate these out into, say, an Asia region, which would also include China, Taiwan, Hong Kong, etc. Have a North America region that would be for the US, Canada, Mexico, and so on. If there are any universal ones such as pay by mail, that could be put into a universal category.
