YouTube improvements is a free Chrome add-on developed by adam.tychoniewicz. This add-on offers a range of useful tools to enhance your YouTube experience.

With YouTube improvements, you can take advantage of features like a filter to show partially watched videos and a filter to show only unwatched videos. These filters allow you to easily keep track of your viewing progress and find videos you haven't watched yet.

While the add-on is free to use, the developer kindly suggests buying them a coffee as a way to motivate future improvements. This gesture shows their dedication to continuously enhancing the add-on and providing users with an even better YouTube experience.

If you're an avid YouTube user looking for ways to optimize your video-watching experience, YouTube improvements is worth checking out. Install the add-on and enjoy the convenience of the partially watched and unwatched video filters, while also supporting the developer's ongoing efforts to make the add-on even better.
