You can find every item on every planet, moon and station.
Obviously we won't be using it, but it's a cool tool to link here. Also shows you how complex the gear and setting are that you'd need such a tool to find everything, and we only have ONE system yet.
Go to "Planetary Survey" for a super-cool depiction of the system: https://cstone.space/survey
You click on planets, moons, etc., and all the areas and shops etc. come up.
Don't stay too long on the site because you'll be tempted to cheat.
