After that the new theming system RRO/Layers came out, I started developing new themes. While it doesn’t permit to customize fonts, bootanimations etc but only the system graphic (at the moment I’m writing this!) it’s awesome because you can really let the user customize the system in a more depth way compared to theme engine. You can for example have different color versions of the theme, let the user choose from different versions of the apps themed (example: have two different types of settings app to choose from). Now the system evolved into new theme engine Substratum!
