In a 1-1 iPad environment many assignments get completed using Apple Pencils on .pdf documents. Whenever this happens it would be great to have the ability to pass feedback back and forth quickly between the student app and teacher app without forcing downloads of documents after each instance of annotated feedback.
For instance, a student takes a test by writing on a Note or in Notability and submits. Teacher then gives handwritten feedback and suggestions. Student then does additional handwritten work and re-submits. The link below gives a video of this actually working in another app environment. If Canvas could include this functionality teachers could streamline their workflow and keep all work in the Canvas ecosystem.
