That would be my #1 desired feature to add to this app - syntax highlighting for the Jison grammar. Since CoffeeScript and Handlebars are written in Jison, you'd think someone would have done this already, but I couldn't wrap my head around the Ace highlighter implementation for those languages. It didn't seem to be as simple as "plug in this Jison grammar and get a highlighter." If that were the case, it would be easy, because Jison itself is written in Jison. :)
