Hugo vs Tinderbox

So, I'm looking at both of my blogs and thinking that this one at daily.baty.net does the best job of wrangling shorter and longer posts and has my preferred group-by-day format. But it's built using Tinderbox, which I love, but I get twitchy not having my usual nice folder full of plain-text Markdown files. I'm trying to reconcile the non-plaintext/markdown aspects of Tinderbox with getting the desired output.
