I’m also an interaction designer. Not sure where the status of this is? It’s 2018…
I just wanted to add how important this integration would be. For me, a way to import Sketch and maintain the layout and layers would be awesome and save so much time! I love using Hype and mostly use it for prototyping and sometimes authoring production ready elements.
Even Sketch can do animations now and InVision Studio is promising. There are a bunch of other prototyping design tools starting to integrate animation. The thing that no one has seemed to pull off yet is that designer to developer handoff. It’s getting better but man, Hype could bridge that gap.
If you were to incorporate modern design tools like Sketch—I’m telling you, you’d solve an important problem and make many designers and developers extremely happy.
