There have been multiple times when I meant to message only one student in class, but the message ends up going out to the whole class. Sometimes this happens even when I thought I had selected the desired student's name. It would be amazing to
A) when the message is going out to a whole class, have a "are you sure you want to send this message to 45 recipients?", so we can catch ourselves if the message is only meant for one student
B) have a "recall message" feature. Yes I know that many students have Canvas messages forwarded to their emails, but anything to reduce the places they can read messages that were not meant for them.
