The little green / red indicators that show up in the lower-right when an enemy is sighted are very useful, but currently it can be annoying when you have a large number of troops and are trying to figure out who, precisely, currently has a particular enemy in their sights, especially on large complicated maps.
It'd be neat if we could right-click an "enemy sighted" indicator to cycle through every soldier, if any, who currently has that enemy in their sights.
