Currently, the only way to discuss a gold transaction is to copy-paste the whole log line to someone. If the transaction ID of the gold transfer was visible, we could refer to the unique ID instead for total clarity (and also a bit of privacy depending on the situation)

i guess my question would be why? who would benefit from this change?

High frequency traders, people asking for refunds, S/A forum too probably. It just makes it easier to pinpoint one specific transfer.
