I also ask to be able to hide any post instead of just pinned posts. This would allow for way more efficiency because the majority of posts that are at the top of my feed are regurgitations of posts with new comments, of which the majority I didn't comment on and don't need to see.
By doing these things I would have the ability to drastically clean up everything and make it to "post/notification zero" daily! As well as saving a lot of useless scrolling and being able to effectively help more people! Nirvana!
