hey there . i would really like that you could see a statisical screen of the cities you have - added with a quick build button - so you can click a build que on the list without having to shift between the various cities on map. - this would make managing a huge empire easier.
here i would also like to have added that you can see how many caravans a city has going for it - SINCE currently its very hard to keep track off!
---
Units i would also like to get a more detailed overview off since its lacking - and when you wanna find all your units that you wanna scrap its hard to track them all down at times during big games.
---
here there should also be one seperate for heroes - so you can quickly click them and see how they are equipped and their stats and xp and such.
including in this i would really like a item transfer system that either could cost gold (hire a messenger to take a item and travel to a heroe (from a heroe - dependign ion lenght this messenger makes it and delivers the items - OR - even a spell that allows you to transfer items to other heroes - perhaps even from a stored vault in a city. so any item bought from the city can be collected quickly and easily by a hero in the field. (that has essence)
though basic UI overview would be the mnost prefered thing here
