You may already have this in mind, but I would like to see an Army or Unit List be available, probably as part of the Kingdom Report, so you can see all the units your kingdom/empire controls at a glance.  I'd like to see the list include the units name, location, number of people in the unit, unit level in the case of the Sovereign or a hero, and status such as guarding-moved-unmoved-etc.  At the very least, unit name and location would be nice.  Clicking on any unit in the list should take you to said unit so you can give it orders.  This would be particularly helpful for mid to late game once you have a large number of units and heroes under your control.
