Last week, Kyle Ledbetter gave an amazing presentation covering the standard set of core UI elements for the frontend and the backend of Joomla! 3.0. Kyle is a principal usability engineer at Ebay and leader of the massive JUX effort. You can access the recorded version on the Joomla! Youtube channel. Kyle explained how the new UI is not simply a front end or back end template, but rather a set of common UI elements for everyone. He explained how developers can contribute to the JUI core, and help to maintain the best practice of using a common UI, if they note a missing element. Please stay tuned as there will be a follow up webinar on this project.
