I'm just getting started designing an app with Framer and Sketch. Sketch is set up with non-retina artboard sizes. e.g. 375x667px for iPhone 6. When I import my Sketch file into Framer Studio, the iPhone 6 viewer has retina dimensions (i.e. 750x1334px) so the designs are half size. How do I modify the import script so that everything is imported at 2x scale?
