still wish that it would ask you if your sure.
Absolultely! Along with Alt + clicking on a Leader's name to declare war...
To go through diplomacy menus for declaring war is a 4-step process... one slip with the keyboard (easy enough to do if you Alt + Tab or use the nearby Shift key a lot for hotkeys or even Ctrl + click on a Leader's name to save time when you want to trade) and BAM, you're at war with your long-time buddy!
The same with Resource pillaging... it's a rare enough thing that you'd want to do for it to warrant a confirmation dialogue.
The same can be said for deleting a stack of units... if I recall correctly, clicking on the Delete Unit icon for a single unit will give you a prompt, but clicking on that icon when you have 2 or more units selected will immediately delete them... I'm not about to "test" this functionality in my current game to back up my claim, but it's what I recall.
And then there's the MISUSE of confirmation dialogues... move onto a non-enemy unit in neutral lands and BAM, you're asked if you want to declare war. Ummm, couldn't you have at least asked us to have held down the Alt key when moving the unit if we wanted to declare war in this manner?
Sure, it's great that if you don't have Open Borders with an AI and you attempt to move into their territory (say, to capture a Worker) that you get the immediate option to declare war on them. But what's the tactical advantage of striking a unit in neutral lands, a location where you are just as likely to want to send your units to scout as an AI would? Not much tactical advantage at all, but a definite huge disadvantage if you accidentally agree to declare war... and war on whom if there are two different AIs' units on the square? The "confirmation dialogue" (which isn't really confirming something that I indicated wanted done in the first place) doesn't even specify against whom you are going to declare war (at least, that's what I recall--again, I'm not about to blow up my current game just to confirm my memory on this point).
the double of a stupidly small number, is still stupidly small
Perhaps, but when you start building those Forest Preserves and that value grows to a somewhat reasonable, albeit still small, number, you will wish that you could easily double that number's value!
