The X-ray mod is invaluable to see the internals of a build and for part placement. It would be terrific if this could be merged into the base game, with this enhancement: the ability to colour-code parts by attributes like massScale, fuelPercentage, deadWeight, etc., one at a time. Meaning, if I select massScale as the attribute I want to see, the parts are shaded with deeper shades of red for greater massScales.
