I was a bit offended at your comment at first, but after much thought I must say you're right. We could have shown an example using lego-build to quickly create a React hook.
I've been thinking of a good comeback but I have none, we should have shown more of the tool's flexibility. But just to clarify, the tool actually *is* as flexible and powerful as it claims to be. We'll try and show more of that on our landing page
Thanks for the feedback! If you're a front-end developer you can try lego-build out, or tell your friends about it.
