Works great, does exactly what I want.

Does not have the bullshit paywall hassle garbage that the DeArrow dev uses. For that alone, I'm donating to Pieter.

Could we have a customisable list of channels to disable it only for those within?

If you hate soyface thumbnails and Daily Mail style RANDOM capitalization of video TITLES, then this is the add-on for you! My YouTube home page makes me far less ragey since I installed this add-on. Highly recommended!

Doing Gods work

I don't personally care for title reformatting, but the thumbnail replacement has been 100% reliable and priceless for years.

I tried DeArrow (what seems to be this extension's current biggest competitor) too, in many different settings configurations, but somehow this one is still better.

better then dearrow bs

It does the job and efficiently.
As soon as it's on I compared the result with a private tab (didn't allow the extension on it) and it's obvious the difference it makes in my ability to focus instead of having clickbait bs on my screen.
This is immediately going on all my devices, alongside Ublock and Sponsorblock.

Exactly what I was looking for

you are genius

Great extension to see actual videos and not spammy clickbait thumbnails

Works right off the bat, does what it says. Can't always agree with the selected replacement thumbs, but on the whole, it's good. I only wish that there were some option to whitelist specific channels, because not all of them use clickbait thumbnails.
