besides the actual content, this is an amazingly nice card_mod for the markdown card 
Id strongly suggest you post this in the card_mod thread, so all can learn how to nicely display a Markdown listing.
This warrants its own section in the example listing at the top imho.
Id probably want to add some scrolling there to keep the header visible at al times, but we have tools for that using the <p> </p> , just have to find the correct spot for adding that
very nice! thanks
