Show HN: Forms within buttons (github.com)

That's great. I always want to do that but never do.

There could be a little "how to" section showing what exactly do we have to do to use it. I tried to look at the sources, but they're all minified (why minify so little code in an example site?), including the HTML. It is very difficult.

I really like it. Only issue I see is that some user will be confuse about what just happened.
