This adds a configuration interface and renderer that makes it easy to put all the pieces together which are required to get a 2.5D effect. It allow for configuring some of the styling and is meant to create an easy-to-use setup. Since every part of the system is built around QGIS' internal rendering and symbology engine, there is much to fine tune. To get all the possibilities, just change the renderer to a graduated, categorized or single symbol renderer upon creation and you will find full access to improve the style to your needs.
