the only thing it need is a button for "already watched" or "i dont like video" in front

It works, has a github as well. Someone said there was no way to turn off the "do not recommend channel button", but that is an option currently in the settings. Awesome, thank you!

Finally someone did it. Thank you so much!!!

A super-good extension. Can you release it for chrome?

Absolutely essential for heavy Youtube users like myself. Thank you for writing this addon!

Oh man, this is great! It really helps a ton to have a dedicated button visible.

My request is to give us an option to swop the buttons around (I think the thumbs down will be used way more often than the other and is easier to move the mouse to if at the bottom) or hide the X button.

Thanks Dev. This is a great extension!

EDIT - Version 1.2
Thanks, Dev!! Works perfectly!

Five stars, good useful addin, but sometime when I click on thumb down button (not interested button) but it works as "Don't recommend channel" (this issue occurs very frequently). Could you check it?
And one more, could you add more room between these buttons to avoid accidentally clicking? Currently, they stay too close.

HELLO, TODAY IS 12TH SEP, I SENT 2 EMAILS OF CONTRIBUTION TO YOUR MAILBOX ME@LIAMOZOG.COM, BUT NO RESPONSE TILL NOW. MAY YOU CHECK YOUR EMAIL? Thanks.

Excellent tool, cool dev adding features.
