I really like the espionage tab, but it can be improved a lot more. Why not make it like all the other tools out there and just auto update self intel for your whole kingdom (or atleast give the option for the monarch to allow/disallow this).

And then add in more information for enemy kingdoms (atleast when in hostile/war).

This would really help out weaker kingdoms and close the gap a little between top kds and bad kds.
