Interesting. I had not seen FlatDoc (
http://ricostacruz.com/flatdoc/) before. Similar purpose to what I was aiming for with Benchpress CMS (demo:
https://srpeck.github.io/benchpress/ and repo:
https://github.com/srpeck/benchpress). Not a huge fan of putting all the page-building client-side though and breaking the lightweight HTML web, regardless of how fast it can be.
