Quick Hotkey

Adds a hotkey to YouTube so you can quickly add them to your Watch Later playlist. Just mouseover any video on YouTube, press W, and it'll appear on your playlist so you can get back it to it when you want! Updated to now support all languages. Thanks for your patience! 🫶 I want to keep this extension as lean as possible, but if you have any functionality ideas, feel free to put up an issue on the Github repo.
