A fun project plugin. Thought of this after discovering a software company had a message about their open positions in the console. I was just curious about the tech-stack and still got served content lol. I added a message for all my visitors too, go check it out. If you don't see anything, make sure your browser console is configured to show logs.

This code can be pasted into the functions.php file of your child theme or, download and install the plugin for simple code activation.
