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.
This, or something like it, is actually on my TODO list. It will become particularly important as ox carts are removed entirely and all food transfers that don't involve traders must use caravans.
