Hey so I'm not sure if this has been bought up, but a good idea would be maybe allowing the option of changing the currency value based on where you are situated? Like I know for someone NOT in the US or UK, having to always add up can be a bit annoying after a while, lol. So a currency converter option, is what I'm referring to. It can either be a scroll down option above in the main menu, or something you can adjust in your own personal User settings.
I don't know if this makes any sense. If not I can try and explain it a bit better. :)
