For expansion/patch
Separate HQ's for air and fleet units, making it easier to build a fleet, so combining a CV group, an escort group and a transport group and getting a combined fleet.
When reinforcing being able to chose on the map the unit it reinforces too, ie. select the HQ or unit that will get the reinforcement.
When selecting a HQ to attach the unit/HQ to it would be nice to be able to see how many divs/HQ a HQ already have, same with reinforcing.
That the mission frames remember the settings from last time.
Being able to give resources to allies in war.
That your partners in crime doesn't feel that threatened by your actions that they wont trade even if they need the resources.
That you can give your allies credit, not just ask for it.
That you can add/remove (on map) brigades from/to AI controlled divisions without having to remove it from the line of command and reinserting it.
That you can check what the HQ's "think" by holding mouse over them, the current messages for lower level HQ's are not that informative (or they don't think and let the higher level do it for them), also the highest level HQ could tell what its plan is.
About the patch, Its good your improving the AI a bit (I like it improved a lot in the expansion) its frustrating to see the AI mill around and hang back where it should storm forward (Germany in Poland) and storm forward at other times to be surrounded as it doesn't protect its supply line (Japan invasion at Shanghai, storms forward, Chinese contains and envelops, Japan doesn't withdraw as reaction to protect its rear, so much that China can attack Shanghai killing off 20 Japanese divs).
That transports(troops) and transports(convoys) be named transports and convoys.
