I think there is still a use-case for mark as unread. Here is what we have currently:
- Unread in inbox: Never opened.
- Read in inbox: Opened at least once, likely requires further action.
- Archived: Done with message.
Sometimes I have a message in my inbox due to a conversation with a user (as a staff member). I wrote something to the user, and am waiting for a reply. I’m not done yet (as I will write again if I don’t get a response in a reasonable amount of time), so I won’t archive it. But, it isn’t urgent, so no need to mark as unread. Then I get a new PM. It is important, and needs a well-written response. But it is the end of the day, and I don’t have time to do so now. I want to mark it as unread so it is very clear to me (or in a group box, everyone) that it needs to be dealt with. Does that make sense @sam?
