Control for including Plug-in Pages in Menu

I don’t know about site params in CSS files, but you can take advantage of the fact that we are allowed to add Hugo partials to <head>. Something like this:

{{ if not $.Site.Params.show_stats_in_menu }}
  <style>
    nav a[href='/stats/'] {
      display: none;
    }
  </style>
{{ end }}

I would like to +1 your request to have built-in support for this. Would it be possible to list plug-in supplied pages along user created pages, @manton, and allow people to decide if they should show in the menu?
