This is pretty neat! I've been thinking of having a goal of writing one article + presentation every month, and this is the perfect workflow to accomplish both - write the article draft in markdown format, and then run this tool when ready to publish. Curious about a couple of things: 1. Is there a way to add notes to the presentation? 2. Is the {.big} notation standard markdown, or something specific to this tool?
