This mod reorganizes the trade UI into a two-column layout to make it clear what items the colony has vs trader has, who is trading, and how much it will cost.
Right-click on the ">" and "<" buttons to add the max/min amount of items (like the vanilla ">>" and "<<" buttons)
I always found the original trade UI frustrating. It is difficult to find what items I want to sell among the huge list of junk the trader has. What do negative vs positive numbers mean? Why is the cost of the trade so far away from the accept/cancel buttons?
Safe to add/remove from saved games at any time
