About YouTube Watched Marker

A lightweight extension for Chrome on YouTube.com where you can hide the videos you've already watched. Its main functions are: * Hide or show videos with one click. * Hide or show shorts with one click. * Making a backup of all watched videos (can download as a .txt file). * You can adjust the opacity percentage of the videos you watch. * When your mouse is over a video, you can press the W keyboard key to mark it as watched. The watchlist is kept in the Chrome cache. Therefore, you can back up your watchlist from time to time and upload your backup in case your Chrome cache is deleted. Problems: * If your page is slowing down due to YouTube's non-refreshing redirect, manually refresh the current page from your browser for faster page loading.
