Embedded Links in WordPress Chat: YouTube, Vimeo, and Rich Previews
A messenger that shows a pasted URL as a plain blue link is missing one of the modern messaging UX defaults: when someone shares a YouTube link, a Vimeo video, a tweet, or a product page, the messenger should expand it into a rich preview with the image, title, and (for videos) an inline player. Better Messages has supported embedded links via WordPress's native oEmbed system since the early 1.x versions — paste a URL, the preview appears in the message. Click the play button, the video plays inline without leaving the chat.
