Add read receipt to chat; i.e., awareness of whether a user has seen a chat #1499

When I'm requesting help I need to know if my helper has read my message. I'm marking this as M-medium because I imagine that instructors/TAs want to know if a student has read their message.

I'm marking this as high. I'm also assigning you, because this is a really good idea, worth doing, and I think all information needed to implement this is already in the browser, so this might be pretty easy. Look at what other chat programs do to indicate "read receipt" information for inspiration...

I would be in favour of closing it without implementation:

it was opened for a while and I don't recall requests to have it
it is actually tricky to implement "correctly", in particular Facebook and WhatsApp have this support and from personal experience sometimes people read stuff which is not shown as read because they read a push notification (or the email sent by CoCalc) and sometimes they don't read stuff which was shown on screen and thus deemed read. In some personal cases the consequences were quite substantial ;-)

I've never seen this issue before. However, I think we have to implement this in order to be able to show users what they have and haven't seen, which is a feature request people do make. E.g., if I want to know which messages i've missed in existing threads, we have to store somewhere whether I've read those threads. It's exactly the same data as "add read receipt to chat".
