I'll start, here it goes:
1.)
Optimize the interface for widescreen monitors. Pretty please with a cherry on top.
Woot. Good call.
I could/would help with that one..
1.a)
My idea:
Also a redesign of some areas for gameplay reasons could be done.
F.e. delete the obsolete theatre tab from the productions menue.
Delete the Theatre forces button productions menue. This was, afaik, also only used in early HOI3 version without LUA-ai-production.
Let us build prov buildings only on the map(Advantage over ai now if we build rows of IC/AA etc. and place the at once on one prov..)
2.)
I always dreamed of having a operational planning mode like this for giving your AI commands orders, really disappointed that this only serves a function in MP.
2.a)My idea:
Maybe a good idea is to being able to set theatre and allied objecives in that map mode?
So it could be used as a operational planning tool already!
That would be relative easy to implement and also a sufficient/efficient sollution.
2.b)
Additional idea:
Adding a priority lvl to the goals woulbe be even better as the ai would know where to spend more effort on.
(That might need additional ai coding for the strat ai, but if that sort of priority is already implemented then it would be easier to add maybe.)
2.c)
If such a priority lvl is implemented, then an "offensive supply modus" could be added too. F.e. just have an different SUPPLYPOOL_DAYS value for units with priority lvl one(out of three f.e.). So these uits would just start to drag more supply with the current supply mechanism, and thus no change to the current supply code is needed.
3.)
Be able to set the stances of the Theatre and Fronts in the Theatre view tab.
And have the ability to change the stance via event/decsion/lua.
Also set allied objectives via event/decsion/lua..
