Quick Watch Later

It adds a "Watch Later" button to YouTube video pages, allowing you to add videos to your "Watch Later" playlist with a single click. This works by automating the process of clicking the menu, selecting "Save," and then adding the video to "Watch Later."

• If the video already exists in your Watch Later, you will be prompted to remove it or do nothing.

Note: It will only work if YouTube is in English. You can fix this manually by changing line 41: button.textContent.includes("Save") to something like button.textContent.includes("Save") || button.textContent.includes("(Whatever the save option is in your language)")
