Suddenly occured to me that I can find the link myself by temporarily making my post type show in the nav, lol.
Update: Ok, get access denied once I change my custom post type back to: 'show_in_menu' => 'frontpage'
That code makes my "Front Page Panels" appear under a menu called "Front Page", which includes other options specifically for the front page.
Is there a way to get a link to manage that? Why is this plugin so difficult. Why is it passing 'order-post-types-frontpage-panel' instead of just 'order-post-types'. Can't the post type be derived from the &page= variable?.
This is too troubling.
