Extension to Disable Annotations and Cards

YouTube "cards" pop up in the top right corner of a video, serving as an annoying distraction just when a creator is making a salient point. The premier extension to permanently disable annotations and cards is the YouTube Enhancer. It targets the specific overlay layers rendered by the HTML5 video engine and assigns them a transparent property. This allows the video to play out naturally without disruptive popups begging you to click elsewhere.
