[Feature Request] Add a reveal/show read posts option on the post page

[mike-to-spec]

Would it be possible to add an option to hide read posts on the post page next to the sorting settings?

There are some communities where I don't want to see the read posts and some where I do (because of pinned posts, etc). So, setting the profile to not show read posts means I can't adjust this on community levels.

Thanks if you can.
