Rated 5 out of 5 stars

Definitely 5*! Also do you have any plan for Firefox Web Extension port? I tried to use foxified to install the new Chrome version but it does not seem to work, at least with Youtube new UI.

This review is for a previous version of the add-on (3.13.4). 

The current version already embeds a WebExtension, and I want to keep this up for a while to allow preferences to be migrated.

YouTube still works for me on the current version. If you are seeing anything different, can you mail me and share some screenshots? YouTube likes to push out experiments to some users, so it is possible that you see something different than I do.
