Feature request: Custom currency

Hi. My currency is from Venezuela (Venezuelan Bolivar VEF). I signed up to WPMU a few months ago and was giving a workaround for adding my currency to the dropdown menu of the Membership plugin currency settings.

I'm writing to see if this can be officially added as a feature request since I think that for plugin that offers a paid service it is very important that it can support every currency. Maybe adding a "Other" to the dropdown menu which would enable a text field. It's what I have to do anyway with the workaround.
