In reply to janikvonrotz.

I second this.
A real useful feature would be a native way to insert code by using shortcodes, just the way CJT plugin allow to use. BTW, the author of that plugin is nearly going to bankrupcy due to the lack of premium version purchases. It is really one useful plugin, unknown for others, but capable of insert any kind of code (HTML/CSS/JS/PHP) with a single shortcode, or even in auto mode in the taxonomies you specify. It's like Shortcode Ultimate with steroids. That guy should receive some bonus, interview or something so others take note of its usefulness.
