Currently the OOB editor is not intuitive, where you build units in the order: Army > Corps > Regiment > Division > Brigade > Battalions/Squadrons
I'd like to see the option to build from the top down. Currently I can define all of my Corps before I fill them but I cannot add divisions and then brigades without first adding regiments. That's not conducive to translations from Campaigns.
I'd also like to be able to define the maximum CEH for each corps, division, and brigade AND be able to randomly fill specific brigades, divisions, and corps (this would also require the ability to define eg Infantry Division, light cavalry brigade) but not so that the randomizer overwrote previously built components of the command but rather that simply filled up any unpurchased CEH assigned to that command.
