Still needs work

Certainly better than Preview, that’s for sure. If you need something to Annotate your PDF, look no further. Works great with iOS app and Dropbox integration.
The one thing that *absolutely* needs to be fixed is the ability to set PDFExpert as the default viewer. Even going by the Finder that does not work. Very frustrating.
