As a high school student and soon to be university student, i take a lot of notes, annotations, etc. sometimes, my teachers give us pdf’s to read or just a document of the information, rubric, etc. it would be so much easier to be able to attach a file to the page, like a picture, that you can click and it automatically opens it. i used onenote a lot in middle school, and that was an function that i loved from onenote. i only use goodnotes now and onenote if it’s really necessary, but i’d stop using onenote all together if they had an attach file function.
