Hello,

It could be great if we have an option in administration panel to use Google's JavaScript API Loader.
I mean instead of loading http://yourdomain/blog/rsc/jsquery.min.js
we could use JS stored on Google CDN:

Exemple:

<script src="http://www.google.com/jsapi" language="javascript"></script>
<script language="javascript">
google.load("jquery", "1.3.2");
google.load("prototype", "1.4.0");
</script>

or directly by putting the URL:
http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js
