I'm using the Document Gallery plugin in WordPress 3.5.1 and am curious about the "menu_order" ordering option, which says:
menu_order - This is probably the one you want to use. Order by the integer fields in the Insert / Upload Media Gallery dialog.
Perhaps I'm a noob, but where is the integer field? I'm not sure if I'm just not seeing it or if it's been removed from new versions of WP...
I appreciate any help on this.
