What's the easiest way of adding more options in the Theme Options of the twenty eleven theme?

Question

Wordpress 3.2 beta comes with twenty eleven. It has a Theme Option panel in the Appearance section:

I would like to know what's the easiest (and extendible) way of adding more options to that panel. For instance, changing the color of other elements?

Answer 1

As you can see in source theme makes some use of Settings API, but doesn't include calls like do_settings_fileds() that would allow you to use add settings.

I would probably try to unhook twentyeleven_theme_options_add_page() call and fork that and theme_options_render_page() to extend it with additional options.

Also I think that unlike core Twenty Eleven wasn't declared to be ready yet. Things might change.
