This is a feature from CK2 that I really miss.
If I'm at war with someone and hover my mouse pointer over my enemys army, the text is white.
In CK2, the text would be red if we're at war, green if we're allied in a war and white if we're neutral towards eachother
You know that the boxes under the sprites are colored?
Yes I am aware of this. But it doesn't help when there's a shitton of troops in the same province.
