Looks nice. I don't know much about modern UI development and often I want to just quickly add a nice looking UI to some of my throwaway/pet projects without having to learn all the modern concepts of React & Co. If this library allows me to declare the components I want with a few event handlers (with as little JS as possible) and it does the rest (I'm OK with the default UI if it looks nice enough), I'm certainly going to give it a try. And I also wonder, what's the opinion of professional frontend developers on frameworks like this, and why they're not more popular?
