Today Lullabot released an exciting new project into the Drupal community. It's the Form builder module: an AJAX, Drag and Drop interface for constructing forms in Drupal. We hope that it will become the defacto standard in building forms in Drupal, replacing our inconsistent form-building tools that are spread across CCK, Webform, Profile, and other modules.

Drag and drop and AJAXy, but degrades too! No need for JavaScript required.

Overview
The Form builder project reads and modifies Forms API arrays. Using a well-known data-structure that most Drupal developers are familiar with should make for low barrier to entry for utilizing the new module.
The project uses a AJAX-based interface for updating form elements. As you modify properties such as "Title" or "Description", Form builder makes requests in the background to update the element through Drupal's internal FAPI system. The user gets a live preview of their changes without saving the form. This approach means that no additional JavaScript needs to be written by implementing modules, since the rendering is done in PHP and then sent to the client as needed.
