PDFpen and PDFpenPro 8.2
Version 8.2 of PDFpen and PDFpenPro from Smile adds a couple of welcome new features to the PDF editing apps. Both editions now support iCloud sync, enabling you to sync documents automatically with other Macs as well as PDFpen for iOS, and the feature works with licenses purchased from either the Mac App Store or the Smile Web site. According to this Smile blog post, you will likely find duplicate items in your
library after launching version 8.2, but you can delete those duplicates. Additionally, both editions now support tabbed windows in macOS 10.12 Sierra — turn them on by selecting View > Show Tab Bar.
