Great plugin(s). I've tested well over 5 different custom post types/fields plugins and non of them have as near the quality UI and straightforward UX as yours.
The only feature lacking for me at the moment is the ability to upload files to a post type entry. For example, if I'm organizing a bunch of journal articles, I'd like to add the PDF to the type without having to use a WYSIWYG editor just for the upload buttons.
I'm more than willing to test anything you need.
