Just upgraded to the Sketch 49 and saw a whole new world of Prototyping built right in! For the last 2 years I have been using Principle for Mac which is great for quick animations that don't require overly complex events and triggers.
In fact, most of the early design of Cake was created directly in Principle from Sketch mockups. I found recreating elements in Principle, though laborious, allowed for a lot of flexibility and quicker iterations. We used this prototype to get aligned on what we were building and test new concepts.
Later we used this prototype to test user testing and presentations. To many it felt like a real thing and we had to remind people that this was just a prototype and a lot of interactions were pre-scripted.
Now that the newest version of Sketch App introduced the prototyping right inside the app, I wonder if I'll be saying goodbye to Principle soon? In the article it sounds like it is pretty robust with many more improvements to come. So I'm curious if anyone has used it for real projects that are more than just simple hotspots linked together?
