I think it would better to merge current domain checker from:
/cart.php?a=add&domain=register
to the
domainchecker.php
In my opinion domainchecker.php provide better functionalities & UI rather than cart.php. I'm not sure though why there should be 2 types of domain order page.
We've made changes to the Domain Checker in Version 7. The domain checker has been integrated into the shopping cart, and along with the new domain lookup functionality introduced in WHMCS 7.0 including spotlight TLDs and sale groups, is designed to offer a more streamlined and consistent domain lookup and purchase experience for end users.
