Hi @brianliddell, thanks for sharing! I, too, love to stick with markdown wherever possible (for my own stuff; the new blocks and layouts are gold for client projects) and it’s fun to see the results of your tinkering. I may copy an idea or two for my own use 
Special thanks for this titbit:
After several months of using Markdown in Kirby, I’ve only just discovered that there are two possible list spacings available in its syntax
…that’s such a great feature and I wasn’t aware of it either!
Best,
