Custom Fields Labels

Hi there.

I have got used to coding up my custom content types in functions.php. I finally decided I would give CustomPress a go and it really does make things that much smoother.

A couple of things I would like to see however. First, is there any way to change the label on the box of custom fields created in each content type? Currently it just says: "Custom Fields" but I would really like that to be changeable on a case-by case basis. Say for example I have created the "Book Reviews" content type, is there any way I can have the label on the box of custom fields to read "Important Book Review Information" for example?

Also, what are the prospects of other field types, particularly date/time, colour picker and file upload?

Thanks again,
