Good advice. Funny thing is, from May I'm working on a big project, where we use ant extensively. We pushed the limits of almost all the available components, found several issues, enhanced it in our custom wrappers. In that time, I was going through the sources of components several times, not only of the ant itself but also through sources of react-components on which the ant is built.

YET I HAVEN'T EVER INSPECTED THE BUTTON COMPONENT. Would be super funny if I would have found that christmas egg this summer...

Now as I'm thinking about it, we have EnhancedButton, which gets 'block' boolean prop to make it full-width. I was used to that from react-bootstrap and even had the idea to open feature request on antd... In that case I would certainly open the button.tsx...

Anyway, great episode in the frontend world.
