Hi, I'd like to propose the option to delete SENT TRADES or mail if the recipient has not yet opened it.
I made a couple trades in error and was not happy that I couldn't cancel them...
Also, I've been writing mail a lot to people, since we can't often chat in the game, and sometimes we might want to delete a message we sent for various reasons..!
This should really be an option in the game. Please.

It's weird, because on those trades, I went to my Outbox and clicked them to cancel them (the red circle next to the check mark) and the mail would actually disappear like it was cancelled. But then after a refresh it was back... So it seems like it was meant to be an option, but didn't get fixed or fully implemented?
Hope its an easy fix, I know you guys are busy
