Could you add the following features:
1) an option to save the various options selected. So that we can easily import these chosen saved options back again whenever we want.

2) Add a stop button to stop the video at its very start. Sometimes it is useful to check again what was the original starting image of the video. Or when you want to repeat from the very start.

3) In the theater mode, there is an extremely annoying "More videos" option that appears and it is impossible to see below this "More videos" option the comments.
Add an option to get rid completely of this "More videos" option in this theater mode and replace it by allowing instead to be able to see the comments normally instead of this very annoying "More videos" set of video links.

4) Below the description, there is now (sometimes but not always) a summary section that is created automatically. Allow us to chose, for this summary section, the option expanded like it is available also for the Description.

One issue:
Under the section Player, Pause while I watch a 2nd video. It does not work if you watch a 2nd video that is a short video; in such a case, the first video will NOT pause while the second short video will keep running and the sound of the first video will interfere with the sound of the second short video!

Thanks to the developer for this addon.

The extension offers a lot of useful features, but it severely affected my Firefox performance immediately after installation. The browser became noticeably slower, and C.P.U. usage spiked by ~35%. From what I’ve seen in other reviews, the developer tends to dismiss, and deny these performance issues rather than investigating, or assisting affected users; replying with responses in denial, instead of looking into the issue. Unfortunately, due to these problems and the lack of constructive support, I cannot recommend this extension.

It's works fine on PC but not on mobile. Blacklist does not work at all and even freezes the browser.

Abandoned by Enhancer (for YouTube) and, looking for a replacement, switched to this one. I hardly miss Enhancer at all. The only thing I really miss in the change of extension is the comments of youtube, sorted by most recent by default. It seems to me that this extension can't do that. Other than that, everything looks great.

It has some nice options and settings possibilities. But unfortunately, some things do not work properly and my browser (Librefox on Linux) becomes completely overloaded, to the point where it even suggests deactivating the add-on! This has happened several times now and is therefore not usable for me.

Very nice add-on that improves the YouTube experience in many ways. The only feature I currently miss is volume control with the mouse wheel. Would be terrific if this could be added in the future. :)

podrías añadir soporte para desabilitar el doblaje automático de videos

I really like this extension. It makes YouTube so much cleaner and easier to use. You can hide all the distracting stuff, change the layout, and add helpful tweaks that make watching and browsing feel smoother. It’s lightweight and doesn’t slow things down, which is great. The shortcuts and filters are super handy for managing videos and playlists too. Overall, it just makes YouTube feel more organized and personal. Once you start using it, it’s hard to imagine going back to the default version.

so far so good

I'm a big fan of this, but I did come here to mention/ask about the hiding the shorts reels/forcing normal player not working - but I see someone said it's on mobile specifically. I have zero understanding of coding or how to use github except following specific instructions, so wouldn't have a clue how I could add the mobile URL if that other person didn't.

Works allright, but on mobile, you have tonswitch to "desktop mode" to make some features work, like automatically redirecting from the shitty "shorts" page to the actual YouTube page for the video.

Seems to work for me. Haven't come across any issues for my uses

Fantastic add one. Youtube is awful to use on desktop without it.
