Hrqls: The point is to allow a "draft" mode. When you type a draft email, it is not sent. You can come back to it later. That's ideally what I want. The clock has not stopped ticking, but I have a move I am interested in making. If I am multitasking, I could then come back and double check (no pun intended). If the move is still sound and then I can send it like a draft letter to be sent later. The opponent would never see the proposed draft move. So, it's not like taking back a move.
