this tool should has options of minify.

@da0ka can you describe that in details? I'm not sure which options may be needed (I've used the minifier for 10 years and never got such need). I'm also a bit confused about how to divide options between regular mode and babel mode (ECMAScript 2020). Do you think to give different options for both minifiers is a good idea?

UglifyJS 3 and babel-minify has many options. but can't change it on test page.
your idea is good.
