I love being able to take anyone's Sketch UI Kit and see how to do that UI in code. I also love creating animations within it.
Importing from Adobe XD would also be awesome. But I hear that is coming out soon.
I created an overview video about my experience with Supernova Studio if anyone wants to learn more about it: https://youtu.be/LbvroonWtqo There is still so much about this product to explore and try. This is just the tip of the iceberg. They made animations super easy and fun to do. I hear they will be expanding the animation studio in the next couple versions. Really looking forward to this! Supernova is also a great training tool when it comes to development as you can see all the code needed to produce awesome UI.
