On May 17, I did an inpromptu presentation on the Display Suite module for Drupal 7 written by Kristof De Jaeger (also known as swentel). For those that don't know, Display Suite allows you to take full control over how your content is displayed using a drag and drop interface. Arrange your nodes, views, comments, user data etc. the way you want without having to work your way through dozens of template files. A predefined list of layouts (D7 only) is available for even more drag and drop fun!
