If you go to the WP main Dashboard page, the screen options allow you to have 1-4 columns for the screen layout.
When you get to the Add/Edit Post/Page pages (/wp-admin/post-new.php and /wp-admin/post-new.php?post_type=page), the max columns you get to pick is only 2.
For someone who has several custom taxonomies, fields and meta boxes, it would be really useful if I could choose maybe 3 or 4 columns instead of having to scroll down each time to select from custom options.
If this is possible, please point me. I would be very, very grateful! I've searched and found nothing on this.
