I am not very good at remembering the names of my AI opponents. So when [RANDOM AI #1] comes to me and says "I will give you 100 gold to declare war on [RANDOM AI #2]" I honestly have no idea if that is my uber strong neighbor or the guy from across the map.
Suggestion #1. AI Negotiation requests should be made through the regular negotiation screen. An emissary can appear using the same Yes/No dialog you use now, but if you say Yes it just opens up the negotiation screen.
Suggestion #2. I should be able to look at the "Foreign Relations" information while I am negotiating.
Suggestion #3. It would be kinda nice to have a small map that fits on the screen that shows the positions of the various nations. Basically, a non-interactive version of the cloth-map. And then have access to that from the negotiation screen as well.
