Sorry if this has already been mentioned but can we please have a message pop up with something like "Are you sure you wish to sell (whatever amount of whatever item) for the following (whatever amount of whatever item)? Yes or no?" on the trade tab when clicking on a trade?

I've lost count of the amount of times I've got confused and ended up losing resources for rubbish resources when I thought it was the other way round.

Surely it wouldn't take much to implement this simple pop up message giving you one last chance to back out before making a drastic mistake trading?

Thanks for the hopeful and much needed feature addition,
Jay
