I miss this menu, as a user. And once again I'm really surprised by the way user interface changes are decided and conducted...

IIRC all the places the menu linked were already linked from the Documentation menu except the transclusion table, that navap also wants to link from somewhere else. I think I even remember him talking about removing the admin menu completely but maybe I'm wrong.
