PixCodes free WordPress plugin

With PixCodes you can have a shortcode insert interface. The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme. Note: this plugin does not add any style to the output of shortcodes. We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes. Here is a detailed documentation about how you can configure some plugin settings and output.
