Seems like a great start. But even in your prototype demo it shows an unmasked password. The current implementation seems a neat little addition but far from the more nuanced interactions most prototyping tools allow you to create.

The idea of prototyping from within sketch is awesome. I think Silver ..er I mean Invision Craft brings to the table a useful enhancement to a tool whose primary focus is on interface design and the production of design assets. However it still is not an interaction design tool and I have yet to see any of these popular asset production tools rise to the level needed for advanced interaction design.

To me this seems more of a “let’s cram Invision into Sketch” rather than a transformation of the tool. I am in no way downplaying the hard work and amazing product that they have built but as a designer I always expect and ask for more. It is what pushes our industry forward and continues to create invention and innovation.
