The only thing I really want from Sublime (or VSCode) is an API that lets me display an output panel/sidebar with an html engine embedded in it.

Atom provides this - it also provides arbitrary html in the editor itself which is cool but also what makes it slow.

I just want it for the supplementary panels that show build outputs, documentation or other contextual information.

That's enough to let me customize it for our team's usage.
