Awesome Plugin & Suggetion

Hey mate, loving your plugin, working fine.. may I suggest you put something to not only go back but close the box so it goes back to its original state within a post? I say this as when I tried it and then went back, it stayed in the same box area place where you put your details and no way to get back out, the only way was to refresh. Could you also make it possible to change the $ to any other currency ie in my situation it would be the Pound.

Thanks ??
