You can now trade coins with other players. The trade window has a coin box under your offer: type an amount (2500, 10k and 2.5m all work) and press Offer, or use the +1k / +10k / +100k / All buttons, and Clear to take the coins back. While trading you can also drag your coin pouch onto the trade window, or click it to jump to the coin box.
Changed
Both players see each offered coin amount in its own row above the items, and the row lights up when your partner changes it. Changing coins resets both acceptances, just like items.
The confirm screen now sums up what you give and what you receive, coins included, and warns you when one side is giving nothing.
A trade that would give someone more coins than a pouch can hold (about 2.1 billion) is refused instead of going through.
