I use:
App: Goodnotes
Stylus: Maglus or Wacom Bamboo
I want to use Notability, but there are two issues that made me hide it in a folder and ignore it. First off, it doesn't go into dual screen mode when connected to an external display, which is a dealbreaker when you're a teache.r Second, the zoom box has the detection box for moving the box at the end of the box, rather than at the beginning, which is what Goodnotes does. That means you have to write into the detection area, wait for it to move the zoom box, and the continue. In Goodnotes, you just continue writing from the beginning of the box.
Agreed. I like Notability's versatility, but I've realized that it is simply a Jack of all trades and Master of none. The zoom box isn't as good as other apps like Goodnotes. The pdf importation is a great feature, but the pdf pages lag horribly, especially if there are images or annotations.
And the folders UI is atrocious.
