Document Scan as an upload feature. 

 

Reasoning: Currently, for my course, uploading notes is a vital component of grading. Our school has limitations regarding the use of various apps, but if Canvas developed an integrated Document Scanner that allows students to take a photo of their notes or paper assignment, and trim the image to the edges of the paper. Many times, this allows students to submit their work to Canvas either as a PDF or a PNG.

 

Similar apps that work in such a manner are Adobe Scan and DocScan. 

 

This would valuable when working on grading assignments and issuing comments as opposed to simply having a student submit a photograph of their paper assignment or set of notes for note checks.
