1. Messages READ
When you look at your messages sent you have no idea if the other player read them.
This would be a good feature and on the realistic side as it is the effect of your Ambassador reporting back to you that he knows the other country got the message.
2. Trade Agreement
We have embargo and they will introduce restrictions on trade, so why not a Trade Agreement that allows you to trade unrestricted between the two Countries.
3. Research Trade
Allow you to trade research accomplishments maybe 3 or 4 steps back. So if you have Light Tank 4 you could trade the method of Tank 1 or 2 to someone else. Much like what is done with licenses to manufacture etc.
