Feature to be able to see whether the player has read your message

I’d say no, I get where you are coming from but it damages strategy a bit. I like to be able to read a message and choose when to respond, especially when I’m sent say an ultimatum and deal. It lets you buy time, and not lose information.

Agreed

Sure I would want to see this too, but I can see the ambiguity of when it was read out-weights other concerns. No one wants others to know when they're online or offline. In the early game, sometimes I intentionally delay responding just so other players don't realize how active I am.

No. Like the others say, I don't need anyone to check whether I'm online.
