I'm considering to convert the Material sticker sheet into React so that it can be used with Airbnb's React Sketch.app (which renders React code on Sketch). You can then use it as a template (use it as is or modify it) to design Android apps.
Does this sound useful? Upvote if you are interested!
BTW: If you are using React Sketch.app, I'd love to hear your experience with the tool, how does it fit in your workflow etc.
