Comparison numbers for changing weapons / armor

Most modern games will show the change to stats when you hover over a different weapon / armor.
For example, when you are in Equipment screen for a soldier, and you mouse over a different armor in your storage. Have the tooltip show "Armor: 30 (+10)" with the +10 in green, indicating the soldier's armor would increase by 10 if you equip that armor.

When a soldier is selected, show the difference of the hovered stats to currently equipped ones as indicated in the image. This way the player can faster comprehend what the effect of changing the equipment would be. The user can already achieve the same effect by separately viewing the two equipment and remembering the stats but it is not comfortable. Showing the difference to the currently equipped gear would enable faster upgrading.

This is already implemented in the game, though in a slightly different way. You need to drag the item you are interested in to the already equipped slot and then windows for comparison will appear.
