Magento: Want CKEditor to appear on Category edit pages in Magento?

It is pretty common to replace the TinyMCE editor in the Magento Admin with the CKEditor using this extension

However, the way magento ajaxes the form fields into view on the category pages breaks this functionality.

This snippet should help anyone trying to get it to work in app/design/adminhtml/default/default/template/fontis/wysiwyg/wysiwyg.phtml

{% verbatim %}
<?php } else if($editorType == 'ckeditor') { ?>

	<script type="text/javascript" src="<?php echo $this->getJsUrl() ?>fontis/ckeditor/ckeditor.js"></script>
	<script type="text/javascript">
	var pageLoaded = false;

	function applyCKEditor() {
		if(pageLoaded) {
			var editable_areas = '<?php echo $editableAreas ?>';
			<?php if(strpos($this->helper('core/url')->getCurrentUrl(), 'catalog_category') != false): ?>
				CKEDITOR.instances = {};
			<?php endif; ?>

			<?php /* Add CKeditor to any matching textareas. */ ?>
			editable_areas.split(',').each(function(dom_id) {
			if($(dom_id)) {
				<?php /* Remove the required-entry CSS class so Magento will
				allow the contents of the editor to be submitted. */ ?>
				var loopCheck = 0;
				while($(dom_id).hasClassName('required-entry') && loopCheck < 10) {
					$(dom_id).removeClassName('required-entry');
					loopCheck += 1;
				}

				CKEDITOR.replace(dom_id, {
					width : 640,
					height: 350,
					protectedSource : ['(/{{[\s\S]*?}}/g)']
				});
			}
		});
	}
}

window.onload = function() {
pageLoaded = true;
<?php if(strpos($this->helper('core/url')->getCurrentUrl(), 'catalog_category') === false): ?>
	applyCKEditor();
<?php endif; ?>
}
</script>
<?php } ?>
{% endverbatim %}

in app/design/adminhtml/default/default/template/catalog/category/edit/form.phtml add this at the bottom but inside the script tag

if(typeof applyCKEditor == 'function') {
	applyCKEditor();
}
