Mobile Gmail Enhances YouTube Links

Gmail's mobile site has a cool feature that adds video titles to all the YouTube links from a message. They're still links, but you know more about the videos before clicking them.

This also works in Gmail's iOS app and Gmail's mobile web app in other Android/iOS browsers. The message from this screenshot only included a link to a YouTube video, with no special anchor text.
