I play the Banker of CE and find it next to impossible to keep track of where all of the food is at times. If there were one feature I wish the Bankers had it would be to see the following:
1. Location of caravans with food on them
2. Destination of said caravan and ETA
3. How much food they are carrying.
I realize for some of the smaller realms they may not need such info but with over 20 regions it does become quite a fiasco to try and keep track of it all.
