Google's keyboard recently added the ability to auto-correct a word back, which I find really useful when I'm using swipe typing -- usually I'll fix as I go anyway, but I'm not infallible and if I expected a swipe to give me the right word, I might not otherwise notice until I go back to proof-read before hitting send.
