This is amazing, keep it coming Figma!
One of the things that is great about prototyping in Figma, is being able to deep link prototype connections to nested components, since you can access the layer stack (ex: a specific menu item within a menu component).
I haven't had a chance to play with the recent Sketch update, but with Craft, you could only link to the entire Symbol, and creating a hot spot is annoying.
Nice! Now just give me the ability to overlay components on my original page so I don't have to create so many duplicate pages.
Great stuff, just had a quick play around with it. Super-simple to get going.
