Apago's PDF Enhancer may not be the sort of utility every Mac user needs, but for certain professionals, it's a must-have for automating the creation, standardization, and optimization of PDF documents (we rely on it heavily for our Take Control ebooks). Version 3.5 offers faster processing speeds (key in a production environment), improved reliability, clean-up of scanned documents, AES security, and improved font and color handling. With version 3.5, Apago has slimmed the product line, dropping the Standard and Server editions to focus on the Professional and Advanced Server editions. ($349 (Professional)/$1,999 (Advanced Server) new, upgrade prices vary)
Option-Click in Scroll Bars for Jump Scrolling
In Mac OS X in general, and thus in most native Mac OS X applications, hold down the Option key and click anywhere in a window's scroll bar to jump to that spot (rather than scrolling one screen). If you like this behavior, you can make it the default in the Appearance preference pane. For "Click in the scroll bar to:" select "Jump to here."
