Here are mine:
! this is for the signatures area,?can be disabled in UserCP though
www.burgershot.gg##.signature
! Author statistics like posts, rep, etc
www.burgershot.gg##.author_statistics
! Rating a thread, I never do that
www.burgershot.gg##.star_rating_container
! Footer doesn't contain any useful info so why waste the space/distract
www.burgershot.gg##.footer-distributed
! I don't like that floating menu bar so I keep it at the start of the page (so there's more vertical space to read content)
www.burgershot.gg##.haut:style(position:static !important;)
! Online/Offline I don't look at either so takes up space
www.burgershot.gg## span[title="Online"]
Any other useful cosmetic filters you guys recommend?
