Absolute must-have of an extension, been using it since back when it was called YouTube Plus, the main developer behind the project spent and is still spending a lot of work on perfecting it as YouTube updates their layout etc. .
10/10, has more useful features than any other YouTube-related extension I've come across so far, highly recommend for everyone to add and use its features!

I used to give a 5 star review, unfortunately I have to amend that decision until a certain feature is re-implemented. I really like the new interface and design of Iridium and the dark theme is cool. But the one single feature that I use this for above all else is gone now, control volume with scroll wheel when cursor is in the video window.

I've read the github post and understand the creator is frustrated. I've been with this addon for like five years now and have been through all of the ups and downs, the YouTube system completely changing and breaking everything, I feel ya. For now I'm reverting to an old version that still has some functionality for me. The mouse wheel volume control has always been the most reliable feature imo. Literally every other function could completely stop working, but the volume control continued, and that's all I really cared about. Hopefully when the new version has the features re-implemented, I will update and go back to a solid 5 star review. Please focus on mouse wheel volume control and reverse playlist control. That's all it needs for a 5 star from me.

之前的版本就在用，但如果可以把重複播放加回來更好。

Thank you so much for this, I missed YouTube Plus, i know it was a lot of work. thank you for bringing it back.

Not bad, the problem is i would ALWAYS prefer Youtube +.

Perfect app, thanks for efforts!

This add-on actually frees your YouTube user experience!

Its' people like this that make the world a wonderful place. Being the successor to YouTube plus I would like to see a replay button like the previous did.
