Adding a watermark in a PDF used to mean choosing the Document -> Watermark -> Add… command. Instead of merely navigating through some 20 menus on the application bar and toolbars to find a particular function, as you did in Acrobat 9, you must now search through the application bar menus, the icon toolbars, and three sidebar-styled task panes loaded with vertically arrayed commands-nearly half of which are hidden by default. The first thing you’ll notice about Acrobat X Pro is, of course, its new user interface. Sadly, this streamlined interface is not an improvement.
