It would be REALLY helpful to be able to pull up all of my communications (including messages and comments) with a particular student. It is often exasperating trying to find the details of a conversation with one of my students – especially if it the issue was addressed several weeks or months ago. I don't always recall if my remark was made in a message or a comment.
It would also help if there was also a key word/phrase search option.
I am not asking to re-invent the wheel. Search features are routinely incorporated into other online communications platforms.
