eh.
Im used to notability but it isnt as smooth as PDF reader apps like kindle and adobe and iBooks. however the annotation capabilities are limited. Xodo is better, however I didnt see a GoTo page option and I was irritated when I couldnt easily undo an arrow or highlight. Also, the pen mark -up is limited to red and the app doesnt let the Apple Pencil shine through with its magical powers. So continues my quest.
