Recently, a new feature was added to the Canvas App, which allows students to "mark-up" PDFs directly in Canvas and submit them. This is amazing! However, it s only a feature on the App, and not in the normal web browser version for students with Laptops or Desktops. This is a great feature that Canvas has, and I just wish the students at our school (who all have district-provided laptops) could do it too!
This idea has been developed and deployed to Canvas
