Hi @PhilipKrauth, thanks for posting this question! When a student has multiple submissions to an assignment, a drop down menu appears under the name in speed grader where you can pick the submission you want to view. You can leverage this feature to compare, however, there is not currently a feature in Canvas/Speedgrader that would highlight specific revisions made based on the previously submitted version. If you have additional questions I would recommend that you reach out to Support via the help menu within your Canvas instance.
