PDFpen 2.4 Adds Comment Support -- SmileOnMyMac has updated PDFpen (and its form-creating big brother PDFpen Pro) to version 2.4, adding support for PDF comments so users can add editable comments to PDF files. Also new is a drawer that lists all comments, notes, and imprints, making it easy to see what has been added and changed in a file. The comments are true PDF annotations, so they appear properly and are editable in Acrobat; similarly, comments made in Acrobat appear and are editable in PDFpen as well. However, although Apple's Preview can display existing PDF comments, its "Text Annotation" tool does not create true PDF comments, but merely yellow-boxed text objects, and worse, saving a PDF file containing comments from within Preview destroys those comments. Although PDF comments are overly awkward for group collaboration with straight text documents, they work extremely well for creating and sharing comments on heavily designed documents containing both text and graphics. Until now, however, creating and editing comments on the Mac required owning the more-expensive Adobe Acrobat Standard or Professional. Version 2.4 of either PDFpen or PDFpen Pro is a free upgrade for registered users and is a 5.9 MB download. New copies of PDFpen cost $50; PDFpen Pro is $95. [ACE]
