To seamlessly integrate Protopie into the workflow, I would love to see a plugin to do the import job for me from inside Sketch. Often, I have multiple screen sizes (desktop/mobile) in one page and I have multiple files open.
It would be great to be able to select artboards and export/update them directly into Protopie where I am able to start making beautiful interactions immediately.
Good examples of exporting from Sketch are Zeplin and Overflow.
