One thing I find particularly annoying with Canvas is that I cannot directly send an Announcement to all students through their Troy email. This was a feature of Blackboard. Also I cannot respond directly to a student's answer on Discussion Board nor is there an Edit feature, as on Blackboard, where I can do a word count. Blackboard had a Reply button which allowed me to send an email directly to the student with a critique of their answer. Using Inbox is very cumbersome and time consuming, especially if the class has a large number of students.
I would like to see both of these features added to Canvas: Emailing of Announcements to all students in my class and both an Edit and Reply feature in Discussions.
