I guess there are more, so far I like the selection. also, in this screen, a legend of the colours would help. I guess red means war and yellow (which is the only other thing I saw so far) means cease fire, but a definite explanation would definately help.
I believe Blue is peace treaty
maybe so, haven't played that much yet and did not see it so far.
also, because it fits:
maybe the modifiers and total relations should in the same dimension. currently it's percentages while modifiers are in numbers. it's like 20% total, composed of +3 and -1. I'd say get rid of %s and just add up the numers. +3 + (-1) = 2. this has the added benefit that values can go below 0 (which is good, bc. if relations are really bad, it should be accordingly difficult to get them on track again) and can be higher than 100 (or 10), so you have more of a buffer. then, you could color code them. red until +2, organge from 2 - 3, yellow from 3 to 5, green from 5 to 8 and above that blue. or sth like that.
