You are right Avi. Rails is missing this magic dust 🪄🎨 that empowers developers and add beauty to any Rails app. I've used yours and it is wonderful well written. As a developer with front-end and design experience, I started mine UI components to save myself time and work. And after a few weeks I launched Rapidrails UI as a product built on top on ViewComponent and TailwindCSS. While it is not an open source, I'm working on an free one, as a part of Rails Rails agency public kit.
I echo your voice, we need more Rails UI components.
