Nice

Youtube shortcuts not editable. You added a shortcut "[" to go to beginning of video and this interferes with another extension.

Mit einer der besten Erweiterungen die es gibt!
Ein Muss für jeden Youtuber!

Wünschenswert:
Equalizer oder Einheitslautsärke für alle Videos.
Popup-Player im Hintergrund/minimieren/DektopICON.

Is possible to add option to add custom button in player layout. I wanna add button for skip 5 or 10s next to sidebar...

The best YouTube extension by far.
I find the extension very robust with features, easy to understand, and easy to use. Anyone who leaves a negative review is doing something wrong themselves. After 2 years of using it, I've not had the first problem.
It's creator is genius.

I've been happily using this extension for years, until today when I went to the settings page (to try to figure out why my preferred resolution isn't being applied to videos anymore) and noticed that suddenly there is a GIANT AD in the middle of the settings page.

Adware in a Recommended extension is absolutely UNACCEPTABLE, especially since you can't adblock elements in a settings page. This is malware-like behavior. Please fix this.

Out of all YouTube related add-ons, I think this is the most useful one.
Still, if it were possible, I'd give Enhancer for YT 4.8 stars instead of 5, just because of the problem within add-on: *reverse playlist does not work* .
Also, on the "Settings" page, a "save (settings)" button would be appreciated, simply as a peace-of-mind button, i.e. insuring that changes were really saved... but only if it wouldn't be much hassle to make it happen. It's not that big a deal.
I could come up with plenty ideas for features that might fit nicely with EfYT, (say a button sorting comments from the oldest to the newest one... and more), but according to review guidelines I'm not supposed to ask for any, so I won't. In any case, thanks for this lovely add-on.

It never saves my settings.

Reverse playlist doesn't work anymore.
