Also, if I were to hover the cursor over a leader portrait, the other leader portraits could change to reflect their diplomatic status toward the one hovered over. That could bring some of the diplomatic relationship knowledge to the main screen. Not the numeric data, but the general status. For example, along with animated portraits and whatever information that might communicate, the border around the portrait could change colors to reflect "official" diplomatic status. The portrait therefore could be left to indicate the direction the status is going, for one thing. So, if he lowers his sword, for example, and seems more friendly, you relationship would be improving, so you might seek to improve your official status.
