I've used Yep 1.8 and its predecessors for quite a while. However, I'm not yet using Yep 2.0.

While Yep 2.0 is an upgrade in many respects, its GUI lacks a way to set the a date for "original document created." It's rather mystifying that this function, which had a prominent location in the user interface of Yep 1.x, is gone from Yep 2.0.

Instead of treating the document creation date as a piece of editable metadata, Yep 2.0 has decided to use the Mac OS file creation date. This makes Yep 2.0 much less useful than its previous versions to manage documents that have associated dates (and there are many such documents, for example: collections of academic papers, legal documents, bills, bank statements, correspondence…).

Although I would recommend Yep 1.8, I would not recommend Yep 2.0 for this reason. The new interface looks gorgeous and polished—but the fundamental function is simply not yet all there.
