Google has just added an ‘Undo’ feature to Gmail that allows users to take back e-mails they’ve just sent. We’ve all hastily fired off an angry e-mail or forgotten to attach a document, and Google has used Gmail’s short lag time after hitting the send button to its benefit.

I’m a big fan of the undo button for e-mail. It should save a ton of faux pas in the workplace, as well as at home. Check out some other neat innovations inspired by Gmail below.
