Instructors who select Anonymous Peer Reviews are not shown markup tools in Speedgrader - Doc Viewer. The tools are disabled/hidden.
Selecting Anonymous Peer Reviews for students to complete as part of an assignment should not result in a reduced set of grading tools for instructors. Instructors should be allowed to use markup tools to provide feedback to students regardless of anonymous feedback from other students. Students should be able to differentiate instructor markup from anonymous feedback; peer review and instructor grading are two separate activities.
