AS-IS: Damaged (non-infinite crystals - faction/T2, that have been used at least once) laser crystals use 1…N inventory icons. The icons do not display the % remaining, and it is not possible to stack crystals with identical damage
TO-BE: When returned to the inventory of the ship, perhaps after loading a different type of crystals (i.e. switching to Scorch from Conflagnation ), crystals of the same type and same damage will stack and display the damage %.
AS-IS shown with blue-is eclipses, TO-BE with green eclipse.
Reasoning: A great deal of laser-fitted ship-flying players sometimes use Faction and/or T2 crystals. Often, those ships are using identical number of laser turrets, and have those turrets “stacked” - meaning all 3 or 5 or 8 fire at the same time, thus the damaged crystals are at an equal percentage of damage.
UPDATE: Some capsuleers objected, saying that only fully repaired items are stackable.
Therefore, I propose another solution:
Damaged crystals will not be stackable, but will still display the damage. When Sorting the inventory, crystals of the same type (i.e. Scorch M) will sort from the most damaged to the least damaged; undamaged stack of crystals will be just after the least damaged one.
Furhermore, to make it easier to see (i.e. “Do those Conflagnations have enough durability left for an another mission?”), the percentages could be coloured.
In the following screenshot, I have used red for 1-32%, yellow for 33-65%, and green for 66-99% - the thresholds can, of course, be different.
