This is a really cool idea. I've been looking for ways to combine the advantages of a static site with a more traditional CMS-esque workflow (I love Jekyll, but I hate having to recompile my site and repush it just to add a new post -- it makes things like mobile editing difficult.)
My question is thus: how would this work with a blog? The demo video showed how to change the text of divs on a landing page, but is it possible to actually create new pages/posts?
