Trade Menu Module - legodude17/VanillaUIExpanded GitHub Wiki
Trade Menu Module
This module improves the trade menu in two small ways.
">A" / "A<" option
In certain cases, this module will replace the ">>" / "<<" (Sell / Buy All) button with one that says ">A" or "<A", which will instead only move the item until the other party runs out of money. So ">A" will sell all of that item that the trader can afford, and "A<" will buy all that you can afford.
Draggability
This module also adds the ability to drag along the buttons in the trade menu, so sell or buy many items at once.
