Weight indicator for heavy/light/detailing armour blocks icons

Hello,

One issue that existed in vanilla SE1 was differenciating light & heavy blocks, the difference between the icons being quite subtle. With SE2 adding detailing blocks (and I suppose more block models will be added in the future), such difference will only worsen.

Indeed there is a difference with icons detailing blocks being pure geometry, light blocks having some ridges and heavy blocks having some grated texture between the ridges, but it's quite subtle, with ample room for mistake if quickly switching between both (say, having one toolbar using light blocks and another heavy blocks ordered in the same way). I think adding some symbol on the icon would make it more visible, more obvious when quickly switching between several types of blocks.

For example, a weight indicator at a corner of the block icon would immediately tell whether it's heavy (full weight), light (empty weight) or detailing (it can stay without an icon, if regular types do have one).

It could look something similar to this :

Should you decide to add more materials for armour blocks in the future (Aluminium, Carbon...), adding similar icons would also help differenciating between various armour types.
