jQuery UI 1.6 Close to Release
The jQuery team have made tremendous progress with jQuery UI and are close to releasing version 1.6. It's presently at RC4 status. They've completely refactored all the JavaScript and created a new CSS framework to handle all widgets. You can try them out here: jQuery UI. I'm really looking forward to jQuery and jQuery UI being integrated into Visual Studio so that we can create some truly compelling interfaces with it. jQuery UI for the front end and user experience behavior and ASP.NET for the back end.
