Hey Michels,

That's an option I considered too making this module (showing directly in pane).
Since the checkout page already was too long in my opinion, I choose popup.
I guess the page view is meant for adding GTCT text as a menu-link?

Nice that you are willing to enhance the module, throw me a patch anytime you like.

I think it's nice to have options to choose from:
-popup (could be enhanced by checking if thickbox is available, and displaying thickbox popup instead)
-pane

Just my 2...
