How can we improve WHMCS?

We can add one set of default nameservers from Admin area, which applies to all domains.

When we use more than one registrar, like Enom and CentralNIC, for instance, we can't set a default set of nameservers for each registrar.

This makes it impossible to make use of the DNS management interface for domains on both registrars.

We need to add a different default set of nameservers for each registrar.
