The idea behind it is great. Having a minimalist interface that let's you build your components with no sweat; also having an extra help from the component generator. I'm curious on how will it work with more complex components?!
Next to a interface redesign, being able to save your components inside a library would be awesome. Imagine having this as a plugin in Figma and using it's potential? The possibilities are endless.
Can't wait to see what the future holds for this product. Great launch!
