This hack "inject" a link directly unter the textarea which, when clicked, will popup a dialog with a graphical Html-Editor.

There's currently a bug in the support for code tags, it will destroy every br tag within code tags.

To use this, put the below code in your free nodelet.

<link rel="stylesheet" type="text/css" href="http://hollihazhomepage.n
+et/ext/resources/css/ext-all-mod.css">
<script type="text/javascript" src="http://hollihazhomepage.net/ext/ad
