Yeah, I do like working with Tailwind and PurgeCSS and that setup works great. It's a good way of avoiding the unused CSS problem in the first place.

The problem for me is digging into a large existing codebase which has built up thousands of semantic class names and a bunch of nesting in the CSS. I'd like a tool that could tell me what's probably not being used, which I could then use as a starting point for some clean up.
