When you get a list in "Shop PaymentMethods", of the payment drivers added to your system. You are presented with the Generic Name of the PaymentDriver module instead of the name of the particular instance of it.
Same happens when the user is going to choose payment method.
My suggestion is to show the "label" property of the particular PayDriver instance instead of the name referring to the class of the paydriver.
I have submitted a screenshot, edited to hopefully clearly explain this from my point of view.
I think this is a bug, not a serious bug, but in anycase very annoying if you have a PayDriver that is configured in many different ways.
