REPEATABLE BUILD QUEUES! Do I really need to choose between conveniently queuing up all the guys I want BUT having to pay 6 turn's gold up front versus spending only the correct amount BUT having to go recruit the same thing from 7 or 8 Indep provinces every single turn? Why not the best of both worlds? Is it really a question of "What would the program do if your empire doesn't have enough money to pay for all the units you've queued up?" Because I think we're all more than willing to accept the just about any solution to that.
Also, I second site searching that takes into account current searches. That would help a ton. Another idea along the same lines is putting those helpful little colored numbers (showing what level searches have been done) in the target box when we're targetting a site-searching spell. That would be so awesome. Here's why.
I play like this: <press n>, do something with commander, <press n>, oh look here's a site searching mage. <Select cast ritual spell>, <select spell from list>, oh target... This forest looks good, but has it been searched for nature sites? Can't remember. <select cancel>, <right click on target province>, no I guess not, <right click on province with mage>, <select mage>, AND then I'm finally back to where I was when I <pressed n> in the first place. Gosh that was a big waste of time. If only I could have seen what level searches had been cast from within the spell targetting phase itself.
Second autoforge item, that's a no-brainer.
Second Hold Position order, or something, for commanders you don't want to see again for a while.
Absolutely second combining site searching spells into one message, but if that's too grandiose, I at least wish the notifications didn't need to be clicked on. Every site searcher message results in a one line report; how about just making that report the event, so I don't have to click open 7 search messages a turn? AND it's true it would be great if we could hop to the target province instead of the commander.
And second castle-storming battle summary. That just feels like an omission. Why is there no casualty report?
Also, wish I were independently wealthy so I could play Dom3 all day long.
