Understood. I’m not intricately familiar with mod creation but noticed that every item has a rarity level and buyable/sellable property. A good reason to dig it at my spare time.
Yes, we try our best to make the game mod friendly 
. For rarity, if you open up a shop json (ex: basic_resource_shop.json) and set a rarity under inventory it will only sell items with that rarity, e.g:
"shop_info":{ "inventory": { "rarity": "rare" } }
