Personally, I can only really use GoodNotes when it is the only app on my screen, because my normal writing habit for paper is to have the paper at between a 40 and 60 degree angle.

When I am only writing with GoodNotes, I can turn my whole iPad (which is challenging when traveling on a train but still possible). If I have multiple windows open for references, though, it makes this especially challenging and causes my wrist to hurt very quickly. My husband who is left handed also turns his paper the other way out of habit, and cannot use GoodNotes at all without frustration.

I am instead using Z——a (another journaling app) for things that GoodNotes could do better. It is doubly frustrating because my main use is language learning, and I am trying to write my kanji correctly but without being able to manually rotate the page as I need, I wind up with skewed kanji which just hurts my studying.

A simple 2 fingers to rotate the page however much we need could really make a huge difference. I have also used the whiteboard but when handwriting at an angle, I have to either deal with tons of red squiggles or turn off spell checking.
