One I use is called "Unhook". You can use it to block different features e.g. Suggestions, video end screen suggestion, front page feed, shorts. It's great if you spend too much time on YT and going on a cycle of watching suggested videos. Now, I only watch videos that appear in my subscriptions or those that I search for.
I also use Better Subscriptions allowing me to hide watched or unwanted videos.
Why do you have to control-click to select langauge? I couldn't figure out how to have multiple when setting up my account, only just realised reading this post. Surely a simple multi select dropdown would be better.
