- Factions now have resource values tied to them that are normally hidden: Raw resources, building materials, foods, clothings, luxuries, furnitures, artistic accomplishments, weapons, prosthetics/medicine, drugs, etc.

- These resource values can degrade or increase over time via random event or could be influenced by faction location. For example, factions in a lively forest won't be too hard pressed for food

- The lower a factions resource value is, the higher their demand for that resource. A factions total wealth can also factor in: A very poor tribe may have no luxuries, but because they're more focused on just getting necessities, their demand for luxuries still won't be too high.
- These values can be requested or sent via communications consoles to factions you are friendly with. If you caravan to a faction you are neutral/friendly with, you can also see these values just by getting a look around their base.

- Your faction can also have these values, calculated nightly. Friendly factions that see you are especially low on steel when your colony wealth is high may message you and offer to send a caravan specializing in steel, for example.

- Market Zones: A new type of storage zone that designates items that you explicitly want to sell. Colonists will automatically ignore items stored here unless you specifically designate that you want them to be hauled out. (Could also work similar to the orbital trade beacon rather than a completely new type of storage zone.) If you have a comms console, other factions can see what you have in your market zones, and if they have a high demand for the things you're marketing, they may send a caravan that will offer high prices for your products.

- Random/generic caravans will still exist, unchanged.

These changes will allow you to interact with factions at a more economical level and match your supply with demand. Market zones will allow you to make a physical shop and storefront for more immersive caravan trading.

This might all be out of the scope of this mod, but I think it would fit in really nicely.
