The free Metabox Glue plugin was created to make editing content on a WordPress site easier when using an iPad or other touchscreen device. A common issue is that when attempting to scroll the page, the metaboxes making up the interface would be dragged out of place or minimised.
With the Metabox Glue plugin active, the post editor metaboxes are glued in place so they cannot be inadvertently repositioned by dragging, or minimised by tapping.
An unglue button in its own metabox page allows the metaboxes to be temporarily unglued. After ungluing the metaboxes will be reglued if the page is reloaded or if another page is loaded.
