Sort available fields on contact form

I'm grateful for this module, because it has the potential to keep me spending less of my life in hook_form_alter(). :)

However, it would be nice to be able to see all the available fields (the core ones included, like name, e-mail, subject, etc) on the "manage fields" page (admin/build/contact/manage), similar to how CCK does it, so that I can manually drag and sort the fields. For instance, I can't position my "phone" field between the e-mail address and subject fields. If I set the weight at 0, it appears at the top of the form, above the help text. If I set it at 1, it appears beneath the message field.

Also, have you considered tapping into CCK for the storage of these fields, instead of re-implementing your own pseudo-CCK? Just curious.
