On numinix.com the Fast and Easy Checkout for Zen Cart Version that is V1.4.2. Is this a new version or a mistake?

I was also wondering if there is a way to change this module so that it looks the set up that is on thelaughterstore website. It looks similar to this module with some nice addictions. It has it so that has a checkbox for returning customers and the default is set so that the customer does not create an account, but on the bottom they click a checkbox to create an account. When you check the boxes, it expanse to show the new fields.

Also, is there a way so that the checkbox for the shipping address that the default is that the shipping address is the same unless you click on the box to show the shipping fields if it different from the billing address?
