I love the fact that a lot of the meta boxes on the WordPress Edit screens are hidden by default. Did you know that it’s really easy to specify which boxes should be hidden? This is great if you’re building sites for clients with lots of plugins that add meta boxes, but you want new users’ administrative experience to be as simplified as possible.
The names in this array match the IDs of the meta boxes you want to hide. To find the ID, just inspect your screen.
Note that this filter affects only the screen options for new users. Anyone with an existing user account already has screen options set, and won’t receive the new default settings.
