About half the features are half-broken, but at least it's all optional

The settings under "general" and "channel" don't work at all

looking to replace Enhancer for YouTube [for Cowardice in the Face of google]... but this extension refuses to export its own settings. asks for permission to access storage [granted] & then never proceeds to local FS folder choice & never exports. importing settings seems to work. wtf... excessively compartmented settings UI, requiring totuous traversal of modal sub-windows.

Nice

Good addon, but the UI is extremely clunky compared with Enhancer for Youtube.

theater mode blank the player view (graphics part gone, just audio remain playing)

Everything works fine except it doesn't help me auto play videos in playlists since playlist auto play doesn't exist for me anymore and enabling auto play in this extension doesn't work.

the reverse playlist is not working,
119.0.1 (64-bit)

I added this extension specifically for it's function to reverse youtube playlists, but I don't see the button to do it.

I liked features like the revers by age button, but I recently started getting an error where any video with annotations would turn the loop video option on, and disabling this extension was the only fix. I'll keep checking back in case of a fix because I liked it, but for now I need the playlists to play properly more than I need the extras this brings.

Not sure why but this extension really likes screenshots. Whenever I change any setting it takes a screenshot. Not only that, but for whatever reason, when I click on the "Themes" tab it takes 8 screenshots. It could be a compatibility issue with another extension but I can't be bothered to check right now.

Intuitive, but not very powerful.

I wish this extension could add new filters f.e.: for video duration and upload date.

This add-on contains lots of bugs. First; it extends the lenght of player so if video is 16:9 it becomes much more long in player base and i have black bars on top and bottom of the video. My YT home page and YouTube users' profile pages also broken because of this add-on. They solved lots of bugs so i am just turning it off for now, i wish they can solve new issues without any more time.
Edit: "Limit Page Width" solved the bug which i mentioned (video width and home, profile pages). Thanks. But changing thumbnail quality breaks thumbnails to gray boxes.

There's a lot of promise here, but there's no polish. Some features work great, until you move/resize the screen. Some features don't work the way you'd want them to. No volume controls for the mouse wheel. It will eventually be a contender with "Enhancer for YouTube™" but I'll give it 6 more months in the oven until I try it again.

Could you make the custom shortcuts work in another tab or while using PIP? I'd like to use rewind-forward keys from outside Youtube

No update since January 2022.

Youtube has updated her design and the thumbnails won't showing.

Please update this extension.

Disabling 60fps gets rid of HD options on the video which was the only reason I even downloaded this addon so sadly it's currently unusable for me. But the other customization options look amazing if you're into that sort of thing!
