// I highly recommend using the "YouTube: Hide Watched Videos" script
// created by Evguani Naverniouk. This is a flow that I use and find very useful.
// This script also helped me getting an idea of how to add a button to the YouTube AI.
// Probably the reason why I chose to make it look like the icons are part of eachother.
