In the 3.07 release of the SiteStudio, we released some technical features for those of you who want to do complicated things with content sets.
Build dynamic pages with context
Basically, context is a way to add query strings (like size=15&page=2) to your dynamic pages without creating complicated URLs. So you can, for example, display all products from a category (q=category:pants), or the latest three blog posts (sort=desc&size=3).
