There's an announcement over on the Zend Developer Zone today about the posting of a recorded webinar that Zend had concerning some of the latest updates to the Zend Framework - Zend_Layout and Zend_View enhancements.
The problem of maintaining a consistent look and feel while encouraging best practices is what Zend_Layout, as well as the Zend Framework 1.5 Zend_View enhancements, attempt to solve.
The recording (and accompanying slides) cover the updates made to these two components and how they help the goal of uniformity and give a "two-step" solution to make it happen. The presenter for the webinar was Ralph Schindler.
