Yep, worth getting YepDecember 9, 2006
Got a load of PDFs hanging arouund and finding it difficult to keep track of them?! Well, I would heartily recommend Yep.
It is very clever, FREE at the moment, accepts tags and offers a very smooth preview (like the loupe function in Aperture). What are you waiting for?!
PS Mac only 😉 (Surprise surprise!)
