If a war starts between 2 kingdoms that you aren't part of, the only notification is a fleeting note in the feed that's very easy to miss, so you run around not knowing who's even at war until you start seeing the siege icons on the map. If you're an itinerant mercenary looking for work, you have to go to the encyclopedia and click through all the kingdoms to see if anybody's got a war going on. Wars are big news even in faraway kingdoms. There needs to be a popup bubble for all war declarations, not just for the faction we are currently in. The bubble could be a different color and/or the sound effect could be different for unrelated kingdoms to differentiate the alerts from the ones for your own faction.
