Additional address selection widget option?

Thank you so much for this module.

I am curious why a dropdown widget was chosen for making the address selection. I can see that this would be easiest were a user to have numerous addresses stored, however I would otherwise think that displaying each of the full addresses with a radio button or a "select this address" button would be preferable. Could the next release include at least a choice of widget? (Please forgive me if there is some ramification of my request that I am missing here, as I am not a coder.) If so, that would be much appreciated. Thank you for your consideration.
