Great to hear! As I said to @brigandish below (and will shamelessly repeat): if when building the app you find yourself wanting to contribute to the js parser[1] in any way (or even any non javascript-based parser), it'd be much appreciated. That's my biggest need right now, is actually writing a good parser that'll encourage people to try this out.
