Gmail installs its undo button

Google is making it easier to steer clear of the trouble that can be caused by a misdirected or inappropriate email. An option to cancel the delivery of an email within 30 seconds of hitting the send button is now a standard safeguard in Google's Gmail as part of a settings change made this week. The "undo send" feature had already been available for the past six years in Google's experimental labs, but that required Gmail users taking extra steps to get it.
