For anyone wanting a vertically split PDF view, it is quite easy if you are willing to download and compile the source files. Open the MainWindow.xib in Xcode and select the "Pdf Split View". On the right-hand side, select "Show the attributes inspector" and under "Split View" change the value for "Arrange" from "Top to bottom" to "Left to right". Compile and the resulting app will show two PDFs side-by-side when you select "View | Show split PDF".
This is dynamite. I am a student and it is by far the most useful. It has a few hiccups, but that is to be expected, I really have found this useful, if one of these was really cleaned up and pushed towards students I think it would do really well.
it can work on mac
Working on MacOs 10.11 Capitan Ok, so far
I found that every time I tap with 3 fingers a snapshot will appear but actually I just want to look up a world in dictionary. Can the snapshot function be turned off?
