Why do I say “almost”? Because the first release of Editor Features could not hide metaboxes.
I'm happy to say that you can now use PublishPress Capabilities to hide metaboxes. This means that when users are writing a post, you can hide ANYTHING that you don't want them to see.
Why would you want to hide features from your users? Some people do this so that the post editing screen is cleaner and less confusing. Other people do this for security and to prevent users from changing some key settings.
