Looks interesting, but I wish there was a way to alias the component names, since every component class, some of which have common names, take root in the global namespace. (though I suspect that easily enough done manually)
It's basically a code generator for adding standard Phlex components to your project, so once you've added a component to your application you can modify it any way you want.
They’re not in the root namespace. They are instance methods (on the instance of the component) that start with a capital letter. https://www.phlex.fun/components/kits.html
