I’ve hidden the Post and Comments menu items in the vertical menu but Post still shows up in the + New drop-down menu in the horizontal menu on the Dashboard. Is there any way to connect the changes to the side menu to the top menu? Or would this need to be a separate plugin?
At the moment there is no way to edit the Toolbar (AKA “Admin Bar”) with this plugin. While it may contain some of the same links as the main admin menu, internally it’s an entirely separate thing and editing it will require a separate plugin/extra code.
