Great work! Some conflicts, though.... We're working mostly with the admin order entry system, so all my comments are on that:

1) Not sure how you have the "Billing address for new credit card" section setup, but if I leave it blank (even without selecting the "enter a new credit card" radio button), the "Bill to:" section clears. Now, at first, I thought this was an ubercart bug, but I continued testing the CIM mod.... I entered a new customer/new order in, with an address in the "ship to" box. I left the "bill to" boxes blank. I selected the "enter a new credit card" radio button in the CIM module panel, and entered a different address in the "Billing address for new credit card" fields than I did in the shipping address panel. after I submitted the form, the address from the "Billing address for new credit card" fields moved to the standard "bill to" fields. the "Billing address for new credit card" fields were blank.

2) The "Payment" panel is throwing me off a little. Is there any way to hide/remove it from the admin order entry screen? Changing settings on the /admin/store/settings/checkout/edit/panes page didn't do anything. Also, the information from the "New credit card" fields in the CIM module panel seems to jump to the "payment" panel fields (the last 4 digits of the card number, exp date & card type). Wouldn't it make more sense to have these setup as unique fields (separate from the regular fields)?

Thanks for all the work you've done!
