Trade, 5 spots

[Zaonabiuibil]

When trading sets, there is the ever present possibility of scams, because all sets have 5 pieces, while the trade window only allows 4 pieces, so there is the possibility they will scam you out of a piece, making the set worthless and wasting your credits/item on a non-complete set. All this rambling is just to state why I believe all trade windows should allow 5 spaces, so the full sets could fit! Thanks all and I'd love to hear your thoughts on this!
