Better then build in os x viewer, if only there was a night reading theme Needs one more thing that build in viewer is missing! The ability to change the background color of the paper to any RGB color one want's
Skim doesn't have basic measuring tools for drawings, so I'm rating features as poor. It also has a limited help function - it took me a while to figure out that when I opened it, it sits on the task bar but doesn't open a programme window; it waits for me to use Finder to open a file. So I'm also marking it down for not conforming to usual usability modes. However it does look quite pretty and seems to have the basic text markup tools, slightly more than are offered by OSX's Preview application. PS To the user who requested coloured notes... OSX's Preview app offers that.
Easier and more feature-full than OSX builtin viewer.
Skim is very good and helpful. Thanks for the developing team. I would like to suggest one handy function which is in the preview in mac osx: Is it possible that notes color may be with different color and not the same color for all notes ? Thank you for all your efforts.
I have used Skim for 4-5 years; it quickly became my go-to PDF reader and annotation application in undergrad, and I continue using it on a daily basis. The note-taking features are particularly helpful, as are its options to customize the toolbar and highlighting colors. As a grad student with a massive collection of marked-up PDFs, I don't know what I would do without it!
