The Add-on works exactly as the description promises, I didn't have any issues with it so far.
The different options are very easy to configure and all of them worked perfectly.

It's a great and useful tool that has helped me waste a lot less time on YouTube.

I only have one suggestion, maybe it could have an option the user can choose, where you have to type in a password or a string of numbers/letters before the user is able to make changes in the options.
