Great work. Love the live preview. As (another) alternative (with a 5+ year history) may I suggest Slide Show (S9). S9 lets you use your slide show package of choice when preparing the output from your markdown source. So far packages include: Shower [1], Reveal.js [2], S5 [3], S6 [4], Deck.js [5], Impress.js [6] and some more. Note: All templates / packages are Jekyll/GitHub Pages-compatible/ready. Cheers.
