Increasing the interactive coding window size

[kgashok]

The coding window size is too small for attempting say 40-45 lines of code. Is there a way we can pop out that section into a new window and plug it back in?

If someone can implement a button that expands the window then I will merge the PR.

div.CodeMirror.cm-s-xq-light {
  height: 400px;
}

A simple workaround would be to paste this into a user CSS browser extension.
