From the development perspective and from other comments that are here, and also from many articles like: https://dev.to/jaredcwhite/why-tailwind-isn-t-for-me-5c90 or https://dev.to/neophen/tailwind-is-bad-because-i-don-t-like-... or https://betterprogramming.pub/tailwind-css-is-probably-overh... you can see that there are still a lot of people who hate the way Tailwind work with classes. But in the same time you can see that they have a steady grow month over month since April 2019: https://www.similarweb.com/website/tailwindcss.com/ that means some people love the way Tailwind is working with utility classes.
So I think this is a really good extension that can speed up the development process of people who like Tailwind. For those who don't like Tailwind, there are many other alternatives. There is no such thing that can fit for everybody.
Some questions 1. What did you use to create the docs? 2. What are your next steps with this project?
