Have you ever asked yourself, “How can I organize all my PDFs?”
Consider using Yep.
On first launch, Yep locates all the PDFs on your Mac, and shows them to you in a simple iPhoto-like interface. Yep then displays your PDF documents in one place. It’s a simple, intuitive, but amazingly powerful, PDF management system. Yep is actually easier to use than it is to describe.
I downloaded a trial version and purchased it a few minutes later.
