It’s a great suggestion´╝ü
#1 is reasonable, and #2 is luxury. Hmmm…
Like the condition of the product, it was great if the checkout setting was able to refer to the user’s custom fields. So I’m very very disappointed.
But you will surely make this plug-in a wonderful product with a better idea.
Thank you for your time. (For now, My choice is #1.)
