Benjamin Den Boer I decided not to hijack Cyrus's question anymore ;)
I have tried to do what you suggested with the Sketch file I am working on and I get an error coming up in the console. I have uploaded the coffeescript to a gist here:
https://gist.github.com/johnend/7e6fa72d736638e3c548 For some reason I am getting an "Uncaught TypeError: Cannot read property 'draggable' of undefined" in the console. I'm not really sure why because based on the coffescript used for the example you sent me it should work?
