ha funny, I built a similar thing to hide suggestions, so it hides all the algorithm feed on homepage, that is my weakspot. still lets you see subscriptions and search etc. then added hiding shorts too

waiting for extension to get approved but its so slow. seeing yours is already more popular you should include this! i also added a menu so you can config what to show/ hide.
