I really like how attached files and images are rendered inline (i.e., as a little card) when adding to a page in Confluence via the "Files & Images. It would be great to be able to do the same for URLs and links. Right now, URLs and links can only be added as simple hyperlinks. It would be nice if they pulled in a preview (e.g., from the OpenGraph og tag) similar to Twitter, Facebook, and other applications.
