Templates That Have A List Of Blocks & Elements

Hi, does anyone know if any other authors have templates that come with a list of Blocks and / or Elements… similar to this Template - http://trystack.mediumra.re/

I’m not sure how this answers my questions… and it just seems like a plug to your product?

If you search for “page builder” you will find more however very few are even close to the standard of @medium_rare1 ‘s one

Thank you Charlie
