Waiting for a good UI library comparison that focuses on how the library works, how it's customized and how it performs. Instead, they usually focus on stuff like Github stars, which companies are using it, etc. Those are important of course, but it seems like these posts seem to always be geared towards people who are basically creating stock prototype experiences. The first thing I want to know is how do I customize the components? Can I do it the way I'd like (i.e. SASS vs. CSS in JS vs. Tailwind, etc.)? Can I surgically (and easily) only include only the CSS and Javascript that I need... and lastly what are my options and tradeoffs with the build process. It's pretty easy with Ant Design for example to wind up with a huge bundle even if you use a fraction of the library.
