Hi! Which feature/s? 1 star by mistake?

Check again please. v4.1090. - Player features work, appearance features might not (because it is a different layout). BTW: reviews are not for specific bug reports or support, but are supposed to judge the product as a whole.

Wow! Are you using our blocklist? Since when exactly? Please report all details (here or better join us on github) (We don't run much by default. Can't run anything special on channel pages. And you will know or see what features you enabled.)
(Reviews are not meant for bug reports BTW.) Thanks!

volume? fan? no!
check this project out on github!

hi, this volunteer project is a rare and special sacrifice of time as it has grown in amount of features and users since almost 12 years. So wishes shouldn't come with down-voting. We are not negatively motivated, but it just makes some volunteers feel misunderstood and leave. So if you care about any of these features the only good thing to do is join us on https://github.com/code-charity/YouTube.

Please consider the other options following "Hide annotations": Hide cards, Show cards on mouse hover, Hide endscreen.
Also: "This add-on..." accesses www.youtube.com. It runs fine on Android - on www.youtube.com, we are not running on m.youtube yet, which is very different.

Most people are here for specific wishes which are rarely implemented anywhere else at all. but if we implement even more of them we do first have to focus on structure of the the lists of features, so that they wont be too crowded, so that the project will be more misunderstood and fewer users might pay the effort to even scroll down the lists.
