Ajaxian » Ext Being developed by this brilliant programmer Jack Slocum, who's starting from using the Yahoo Ajax toolkit, Ext is apparently a framework that will support more than just YUI. In fact, Slocum has already incorporated into Ext (which is still in alpha development) support for both jQuery and Prototype/Script.acul.ous. Amazing! The widgets on display at the Ext docs site are incredibly sweet... I've downloaded the latest alpha build myself and hope to play with it shortly. So far every widget I've tried has worked great in WebKit.
