Nuebar review for Geolocation

I really really need the selector to be customisable more. I need to be able to place it in my header and I need to be able to shorten it to display just currency code, ie: AUD, USD None of my US customers are finding the selector when they don't use the pop-up. It's incredibly frustrating. Please at the very least, have a shortcode I can install in the header for currency switching.
