Theming
  I have the checkboxes. I want an automated way of determining what themes are
  available if possible, and I need a way to specify the theme on load.

WYSIWYG module
  Add the ability to apply Bespin to a content_filter through the WYSIWYG module.
  The payoff is big, but the difficulty is also.

Add command line
  Currently, if you are in the command line and punch enter, the form submits.
  I need to supress that.

Make textarea resizable
  There is a handle at the bottom. When Bespin is applied, the handle is
  still there, but doesn't work.

Fix clicking in Bespin scrolling to the top
  Moving focus to Bespin automatically scrolls to the top. This could be annoying.

PHP Highlighter
  Write a PHP syntax highlighter for Bespin. Clearly useful.
