There's a javascript (http://blogs.adobe.com/acrolaw/2010/02/add-a-flatten-document-menu-item-to-acrobat/) out there that once copied into the javascript folder (Program files/adobe/acrobat 10.0/javascript) is suppose to place two menu items that will allow you to either flatten a page or flatten a document. It worked fine in Acrobat 9 but I can't seem to get this to work in Acrobat X Pro (version 10.1). It would be fantastic to add this to the Quick Tools menu.
cParent: "Document",
into
cParent: "Edit",
Scripts which create a menu item can't be added to Quick Tools - for that, the script will have to load itself as a toolbar button, and that's entirely different code to the example you're looking at.
