It's a great extension that can do a lot of great things. However,
The recent update this extension has recieved is not very stable and doesn't affect EVERY video. To solve this I would reccomend maybe adding a feature to revert to the older version or toggle back to the less stable new one.

Bonjour, désolé de ne mettre que 3 * alors que j'ai déjà mis 5 * à la version précédente car cette extension est très puissante, performante et indispensable !!..
Pourquoi ?
L’incrustation des icônes en bas du lecteur masque plusieurs infos, dont la durée de lecture et, dans le cas de webcam live, le bouton Youtube "En direct" que j'utilise très fréquemment !
SVP, VITE une mise à jour permettant de choisir l'emplacement des icônes... soit, en bas du lecteur, soit en dehors du lecteur !!... MERCI !...

Hello, sorry to only put 3 * when I already put 5 * in the previous version because this extension is very powerful, efficient and essential !! ..
Why ?
The overlay of icons at the bottom of the player hides several pieces of information, including the playing time and, in the case of a live webcam, the Youtube "Live" button that I use very frequently!
PLEASE, QUICKLY an update allowing to choose the location of the icons ... either, at the bottom of the reader, or outside the reader !! ... THANKS! ...

Pls i hate this new interface, it's blocking all my youtube bottom screen, i can't even see youtube timer. you guys can hide all the icons in a dropdown or something, just take it of my screen for god sake, Thanks i always love your app until this ugly large icons update..
** EDITED**
I some how was able to edit it and take off some icons from "Extension Toolbar", But still the icons are large, needs to be resized thanks.

While I do not utilize all the features this add-implies are available, the ones I do use just work as expected to my benefit. So FIVE STARS for 'enhancing' to the level that advances my viewing. THX

Genial! me gustó mucho el nuevo estilo, limpio y mas accesible!!!

This used to be a great addon, latest update is still functional but the new interface is awful, too fussy and intrusive. Bring back the old look.
Edit - for those who prefer the old look you can rollback to the previous version

M encantó!

Thanks for the new update. Has made everything look cleaner and more modern. It seems to have also fixed the problem where some videos would stay at 0:00 and would then randomly stop a few secs to a few mins in the video.

I do NOT like the last update

Really dislike the update - more clicks if I can still do what I want at all. I've disabled this on all my devices, will look elsewhere.

This new update is great! Only one problem: the autoplay toggle doesn't save. It always reverts to the "on" option.

The new version is awesome!

Excellent work, keep going!!!!

very nice it really enhanced YouTube
