Hi, the word filter applies to our many layout and display:none features. However content-filtering can be the biggest roadmap item since we have not implemented or been asked, most of it. You can read up on it here https://github.com/code-charity/youtube/issues?q=is%3Aissue%20state%3Aopen%20label%3A%22Filtering%20%26%20Discovery%20(of%20Content)%22 )(half of which remains monologues with no user participation) https://github.com/MarcGuiselin/youtube-refined did some, yet only found about 1000 users then. Recently our new "competitor" Untrap has some too i think and is surprisingly the most / only likely developer to be reading our repo and roadmap. (If you can, suggest them not to collab / not reinvent this difficult task https://github.com/code-charity/youtube/discussions/1881). You can give fair feedback and you might not want to frustrate volunteers. We could also flag this ("Misplaced bug report or support request"), but prefer to keep information visible. There is no marketing budget and usually that would leave traces. When driven by suspicion, you might have more fun /success examining code. (You could enhance global security scanners or run your own).
