Adds WYSIWYG-like capability to Drupal by providing buttons to insert basic HTML tags and get a live preview of the rendered textarea on the fly.
The goal is to have it fully integrated with Drupal's input formats and adapt the available buttons automatically.
All buttons are CSS based using the Gmail button technique. There's also quicktags that you might want to check before a D5 version is released. Icons have also been included from that project for now but are no longer being used.
The API will allow you to theme buttons and add new buttons with custom functionality pretty soon. :)
