Here are my reasons: It takes away the hassle of scrolling a hundred times to look for the item you really need, most especially when you've already started picking items to trade and the other player trades something; a box pops-up and says "you are already in trade with this person." 😰 AAAaaAa Lesser time pressure for impatient traders. Idk. Wbu? What are your reasons? Are you for it or 'thank you next'?
