Mit einer der besten Erweiterungen die es gibt.
Einfach ein Muss für jeden Youtuber!
Wünschenswert wäre noch ein Equalizer oder eine Einheitslautsärke für alle Videos.

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.
