YUI-EXT - A cool tool

A friend a work linked me to this. It's a neat javascript package. It's an extension off of Yahoo! User Interface (YUI) Library. It is called yui-ext.

If you are not familiar with YUI, it "...is a javascript library that is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses." (Quote from http://developer.yahoo.com/yui/.)

This library takes the YUI another level. It is a bit hefty at a 345kb js file download for the users.
