Today Smile released version 7 of PDFpen for the Mac. I've been using the beta and particularly like some of the new features:
You can now add a signature field and then later sign a document using your track pad.
OCR Layer Support
I've always known of the mythical OCR layer in PDF files. Now PDFpen can display it. With PDFpenPro, you can even proofread and make changes to the underlying text layer. Boom.
Context Sensitive Editing Tools
Select some text, right click, apply.
Retaining Object Properties
I like my circles orange and my boxes red. Now PDFpen remembers that.
Export to Excel, PowerPoint, PDF/A
PDFpenPro added the ability to export to Excel, PowerPoint, and PDF/A. This is in addition to the export to Word feature that already exists.
I liked the beta so much that I agreed to make some videos for Smile that you can find right here. Below is my "What's New" video.
