Classy Widgets

Do you have client-facing node/add or node/edit pages that you want to stylize or augment? This module enables per-field custom css classes without having to write your own form_alter. Adds configuration pieces at the bottom of the field settings to collect the css classes, and then adds those css classes to that field in the form, at the same level as the field-type-text (etc) on the container.

I currently have this limited to only node/add and node/edit pages. For displays, there are real modules like http://drupal.org/project/field_formatter_class

There is an intention to merge this module with the larger effort at https://drupal.org/sandbox/jasonfisher/2202359 but it has not happened yet.
