One huge thing that could really help this site grow is the ability to set custom prices in all currencies. This is because if we set the price in dollars, the customer sees a funny value in, say, GBP£. For example, £60 is a lot more appealing than £60.73.The awkward conversions make for unappealing rates in other currencies.
If I price something at $100, that’s a nice figure. Converted to pounds, you may see £78.72. I’d much rather make it a flat figure.
