PDF Annotation: Inking
I read a lot statistics PDFs. As I do, I like to write with a stylus on the page. For example, I will write alternative forms of an equation in the margins or write out steps of proofs that aren’t clear. I also like to circle parts of equations that are most relevant (the highlight tool often does a poor job of this). I would really like if Zotero’s new PDF reader could support the ink annotation tool for these purposes, especially as part the iPad app.
