I'd like be able to see the tribute values while deciding on declaring peace as well.
Example:
I'm the king of a kingdom and we're at war with Vlandia and the Northern Empire. My council pushes a peach vote with Norther Empire but when making that decision I have no clue who is paying tribute to who, or how much it is.
This is really frustrating for me as the Northern Empire has 0 fiefs (no castles or towns at all), and 0 prisoners of ours. We own 4 towns, 1 castle, and have 2 of their lords prisoner, but everytime we declare peace, we end up paying them 1k/day. I'd rather just stay at war (they pose zero threat at this point) but I can't see the tribute to know it's not worth taking the peace offer. So I have to save before EVERY peace offer so I can see the tribute value, then load the save and actually make an informed decision.
