Schmitz Smile has pushed out version 8.1 of [1]PDFpen and [2]PDFpenPro, which adds visible snap-to guides that help to more precisely place images, shapes, text boxes, and other objects. The PDF editing apps now display an email address for a self-signed certificate (instead of the issuer), retains size-to-fit font in appearance for form fields, resolves a hang when performing a Save As for forms with required fields, works around a drag and drop issue in the sidebar on macOS 10.12 Sierra, and avoids converting grayscale images to RGB after opening.
