Two simple overlay additions I feel should be added.
Armour Resistance: Displays blast and pierce resistance per block. Blue denotes a high pierce resist, green denotes a high blast resist, and red shows lack of armour. These colours combine as well as show each number.
Examples: A greenish blue 30/20 shows a block has a Armour resist of 30/20. a bluish red 0/10 shows a lack of protection from blast, but not piercing. (Although no armour wall piece exists with 30/20 or 0/10 stats this was just for example purposes)
Combined HP: From green to red to black, this shows the combined HP and Armour rating of each block.
