If the trade beacon was redesigned you could place it outside your base and all resources you have in any stockpile zone would be tradable. But when you have sold, colonists must haul the resources to the trade beacon so the orbiting trader can recieve it. it becomes more convenient to trade with orbiting traders because you dont need a trade beacon in every stock pile. and it makes sense a bit more if you had a requirement that the tradebeacon must be unroofed perhaps. players can get a little more creative with their bases, i know i tend to make just one big stockpile with a tradebeacon in the middle and then a fridge/freezer with another tradebeacon in it. Done. I hope you get my idea. And i hope you like it. Anyway time for me to play more rimworld. Have a nice day.
