Hello.

Is it possible to extends the build in richeditor form widget? For example add a stylesheet while it loads? At the moment I have the following code inside the boot method of a Plugin.php file:

\Event::listen('backend.form.extendFields', function($widget)
        {

            $widget->addCss('/themes/testtheme/assets/css/test.css');
        }
});

This seems to work, but is this also the correct way of extending the editor?
