After using another tool for YouTube for years, which is no longer being developed, I looked at various alternatives. This one was the best alternative that I liked the most. The only thing that really bothers me is the confusing layout of the settings. Everything is just all over the place. That's neither clear nor user-friendly! That should be made clearer. Apparently the developer has never heard of UI design! ;-) But otherwise, it has almost everything you need. Oh yes... and why can't one block "Member Videos"?
Edit:
I have this enabled, "Member Videos" in the sidebar are not blocked.

The most advanced add-ons for youtube. Old school power user tools, not for casuals. This thing need it's own guides and tutorials.

EDIT: After update 3.84.0 the shorts are gone, updating the score

Main thing I want this is to hide the stupid Shorts. It doesn't work for them, they are still there in List view.

Clicking a link should NOT turn that link RED. (#FF0000FF)

Der Wahnsinn! Die Einstellungsmöglichkeiten können einen zwar anfangs erschlagen, und teils sind Dinge aktiviert, die man vielleicht nicht will. Aber wenn man sich erstmal reingefuchst hat, sind die Möglichkeiten gigantisch. Hatte bis dahin den Enhancer for YT, aber der ist mal wieder ausm Store raus und scheint auch arge Probleme zu verursachen, deswegen hab ich mir was neues gesucht - und gefunden. Bin begeistert!!!

Even with all the options labeled as "Might trigger YouTube's adblock warning" disabled, still makes YouTube videos buffer and cynically ask "Experiencing interruptions?" despite me having uBlock Origin on. Disabling Tweaks For YouTube fixes it. I can no longer use YouTube with this addon installed, hoping the devs will find a way around it, since I love the functionality otherwise.

Would love a "Reverse Playlist" button.

Possibly the most well-done YouTube tweaks extension on the planet.

As someone who has tried making extensions for youtube. Dealing with all the dynamic loading, exquisitely made.

i think it's the best add-on for youtube for me (aside from ublock ofc). There is a LOT of options although i wish they were better categorized. It's a bit of a pain when you need to change one setting and you pretty much have to search manually through most of them (in other words category names are bad). Maybe add a search button or get list of changed options. Great addon nonetheless.

Amazing set of features that isn't matched by any of the other YouTube suites.

Unbelievable. The author has dissected YouTube.

The number of features is staggering. There is something for everyone—too much to list in this comment; you have to try it yourself.
Amazingly, every option is explained via tooltips, so you know what to expect. The UI has a clean and elegant style, something that browser addons often fail to achieve. After finalizing your settings, you can export them and easily apply them to any device and browser.

I was using YouTube Enhancer before, which had a fraction of the settings that this extension offers, and some of them didn't even work!
Frankly, the former looks like a joke when put next to this one.

These should be the official YouTube settings, and the author should be employed by Google, collecting big paychecks. This addon simply feels like a part of YouTube.

This absolutely smashes unhook. I found it searching for "make thumbnails smaller" but the more I tinker with it the more features I find that I didn't know I wanted. Even the UI and tooltips are first class.
