Currency Counter in Trade Window

PoE players are increasing and players trade further more than before to imrpove their characters. But the scammers are increasing, too.

Could we have a Currency Counter in the Trade Window so that we can easily know exactly how many currencies show up in the Trade Window?

This Counter could be designed like only work for currencies, or stack-able items. Of course it will be cool if the Counter also works for gears to show the number of linked sockets and so on.

It's just an example.
