We'll create fresh WordPress site with Metabox Glue installed. You have 20 minutes to test the plugin after that site we'll be deleted.
When the plugin is active, the admin metaboxes are glued in place by default so they cannot be inadvertently repositioned by dragging or minimised or tapping.
A checkbox in a metabox allows the metaboxes to be temporarily unglued until the page is reloaded or another page is loaded. This Unlock metabox can be hidden in the screen options for the post type.
