A browser extension to show a hidden element to people with the extension installed

Fri, Jul 20, 2018

I’ve got this idea i want to hide the Agaric-insider-specific links in our public documentation by default, but display it to us lucky few in the know (or anyone who views source).

<aside class="they-live--agaric">
  Agaric's secret browser extension to easily see these notes is documented in our internal wiki.
