Most have for nonchalatt fans! I'm unsure if it has a toggle. It can be annoying for some thumbnails. Someway to toggle it aka. quickly preview original image/without the cat would be great!

New bug makes it so that while I have this extension enabled, all youtube title text becomes small and I lose the ability to sort comments by newest. I'm a vivaldi user which is just another chromium browser. I have a-lot of custom extensions for websites that all work as intended, so I don't now why this makes youtube become so weird. Anyways, I love this extension and I'll be keeping it updated/checking on it to see if it ever works properly again, thanks for this amazing extension that has gotten me to watch a lot of videos I would've otherwise skipped if I saw the actual yucky big red circles and disgusting mr beast faces. I'll gladly come back and change my review later when it works again :) edit - setting toggle schlatt nick-names to off fixes the issue.

This is the best thing I've ever installed. If they installed malware, spyware, or a Trojan on my hard drive I wouldn't be mad.
