Great to see you make such progress. I kinda like that MD is sort of a personal thing from Alex, instead of a theme from a big faceless company.
Personally I would like to see the drop-ins be released in the coming months. I really think that would benefit the current MD community and show potential customers that MD can be extended in many ways.
I'd also love to see more in-depth tutorials on how to create custom pages with code. People like me who use MD for client work allready know how to code and want to make every MD website look unique.
