Hi,
I use a lot of the description Dynamicweb places at the end of the HTML to confirm page ID, page and master template. My suggestion is an add-on
Would be easier if placing something like templatelist=true in the URL would complement those comments with a list of the paragraph ID and paths to the active templates on the page.
I believe this would help debuging (for customer support and site development), having a quick list of what's being rendered.
