I would really appreciate if you added an option to completely hide the video thumbnails (making them grey).

Nice one! Works as expected, running with 'Middle of the video' and 'Capitalize sentence'. Only 'Capitalize Words' doesn't work for me atm ... but the *real* thumbnails are worth it! Love it, thanks to you!

It would be good adding some exceptions, channels trustworthy

Excellent

excellent extension. fuck clickbait.

Makes YouTube great again!

Anyone not liking how it formats titles, there are options to change that.

Great add on. Makes youtube less stupid. I wish it could remove those dumb "YouTube posts" things though. Feature request!

I like what it does for thumbnails, but I wish there was a way to disable what it does to titles - it removes ALL caps from titles so they look weird now and unprofessional. Each word of a title should be capitalized, this add-on makes all except the first word lowercase.

Works as intended! The results are quite welcome, seeing how bad clickbait can be on YouTube.

It would be great if it had a whitelist feature, the idea being that it won't change titles and thumbnails for whitelisted channels.
