Prelude: Each of these features are especially important when working with a high number of orders and doing final check to ensure the sequence is as desired, and becomes even more important when playing on a big/dense map (high # of territories).
ZOOM / MAP POSITION:
Have a checkbox to 'lock zoom', 'lock position' on map, and also to 'move to relevant position'. When clicking on items in the 'Orders' box, the view zooms out and changes the view position. Most of the time, this is very useful, but there are times when I'm zoomed in looking at a particular part of the map and want to see the order from a specific perspective, but this nullifies it and shows a generic view. This applies when playing one's turn and also when reviewing History.
ARMY TRANSFER/ATTACK ARROW:
The arrow indicating army count display needs to be highlighted to a different colour or have a highlighted (white?) outline so it's easier to see where it is on the map - especially when reviewing orders or history.
ARMY COUNT BOX:
The box showing the # of armies being moved/attacking sometimes overlaps the arrow and it's not clear where the destination territory is. This becomes troublesome when there are many territory borders in a small area on a dense map, where it becomes very easy to click the wrong territory and not know it from the graphic (it is evident by comparing the name of the territory on the order, but it's best to just move the box so it doesn't overlap and make it visually obvious).
