Formfilter provides tools and a user interface for doing common form altering tasks. Includes a UI for selecting which fields to hide (passing the elements as values, if possible). Also includes an optional filtering of node forms to promote two fields and then put fieldsets in an 'advanced options' fieldset, to declutter the form. As of Drupal 6, Formfilter is divided into two modules: Formfilter is a pure API module and Formfilter UI provides an administrator user interface for filtering forms.
