So I there I was, I'd gone from the simple province of London to the richest empire in the world, and the biggest target.

All it took was a single spy, suddenly my bezzie mate the Pope decided I was an enemy of God, and therefore an enemy of all my trade partners and neighbours (except England and Scotland, they were surprisingly chill and got excommunicated with me).

I went from managing one or two battles to having to not even knowing who was against me anymore, and that's when I started having issues with the UI.

It's surprisingly hard to tell who's your enemy just at a glance, obviously armies are red, but cities and and country coat of arms all look the same as when they're your friend, so every now and then I'd go to move through what I thought was an ally only to be swarmed by enemy armies.
Scenarios of mistaken allegiances were pretty much constant until I was down to my last city.

With all that in mind, I need a mod that makes it SIGNIFICANTLY clearer regarding friend or foe status in the basic 3D view, going to faction info and the overlays was eating up too much micromanagement time.
Whether it's a green/red glow to the whole country or a big circle around cities etc. I don't care, it just needs to be idiot proofed.
