React to notification

[alya]

It is common for a user to want to acknowledge a message they receive a notification about. At present, this requires clicking on the notification to get to the message, which takes some time.

It would be convenient to be able to reply to react to a message directly from the notification. The highest priority is to be able to give a thumbs up, though we can consider other reactions as well if it's technically feasible without too much additional effort.

This might not be possible since the notification UI does not allow interaction with 1 particular message, but rather a particular notification.

A notification corresponds to a particular conversation in topic, pm or group pm, in the design we will be having in #4842. Hence its possible to reply to a notification (the reply just gets added in the conversation) but we cannot have an interaction with a particular message in the conversation.

Yeah, good point.

I think if we were to do a version of this feature, one behavior that could still make sense is that we'd react to whatever was the latest message we're showing in the notification.
