Scrolling when I move the mouse within a couple of centimetres of the edge of screen - say for example to click on the Tech tree button. Inability to sort lists of stats for cities in the various City info panels, trade destination panel etc. Right side build list wiping out a large part of the name of the city it refers to, meaning I have to go squinting around looking for the city I'm managing. Simply reducing the height so it doesn't cover the city panel would help I think. Unit cycling often scrolls away before the results of combat or action are visible to the player. Future tech and final Culture research should be able to be looped. You could do this in older iterations of Civ. Being able to alter the direction of city spread would be nice.
