At the BlogWorld Expo in Las Vegas, PageLines released "Platform Pro," a drag & drop design framework for WordPress. The product features some nifty CMS design options, a drag-and-drop layout editor, and a fully configurable template builder for creating custom websites.
In addition, Platform comes fully integrated with bbPress forum and BuddyPress community software right out of the box, and additional support for SEO, social media, ad campaigns, and more. Platform's front-end design is based on what PageLines refers to as "sections." These're similar to WordPress widgets (drag-and-drop sidebar content) but according to company works much better for creating cool designs and for use with templates.
The product, Platform Pro, costs $95 for a single license, suitable for multiple sites owned by the same person.
