DeArrow has improved my YouTube experience. I still switch it off for some channels I like (such as SiIvaGunner, for reasons that are obvious if you watch them.) It's best when it has crowdsourced titles, which have actually made some videos more intriguing.

I saw a video thumbnail the other day that would normally be titled "Why Minecraft players built a real life supercomputer", which is way too vague for me to be interested, but the crowdsourced title was "Minecrafters created a distributed computation network to find the tallest cactus," and that made me very curious. I still didn't click it because it was a 23 minute video, though.

I'm also very grateful I don't have to see a lot of clickbait thumbnails. Some of them actively deter me from videos that might otherwise be interesting.

Sponsorblock, which unpads the vids.

Not sure if i'd say that Sponsorblock upads videos, or at least it only does so partially. It does remove in-video advertisement and selfpromotion, but it doesn't (and can't really) change anything if a video e.g. has content to fill like 3min, which gets drawn out to 10min.
