Shopping cart

Hi!
Is it possible to customize the shopping cart so that all fields filled by the user are displayed below it, and not in a separate link? Make a kind of a one-page basket, like a *one page checkout*. I've tried a bunch of plug-ins, none of them suits me. I like the standard design of my template

Or display it in separate fancybox?

Also i would like to transfer the fields of registration in the pop-up window such as pop-up window *login*, that are in this template. Is it possible? Or in fancybox. I want see all userfields in fancybox.

I’m afraid that modifications such as this require extensive changes to the theme’s code; I do apologize but such large changes are custom work that are beyond the scope of our technical support.
