Gmail Improves "Undo Send"

When the feature first launched, I was worried I would eventually adjust to it, and stop re-reading emails before clicking "send". So far, that has not happened - it's effectively a psychological trick that continues to make my emails better proof-read.
Gmail just increased the time you have to "undo". Before the max was 10 seconds. Now you can choose up to 30 seconds.
An outbox would be pretty nice.
I still fall on the "don't send it unless you mean to send it" side, however. My outbox is only used when I don't have internet access.
