How to display meta information (yaml) in the pop-up preview window?

Display front-matter on hover preview

Now that the front-matter is such a big tool, I reckon it may be a good idea to allow the user to select to show/hide meta data when previewing the note content. The rationale is: We are now adding more & more detailed front matter in our notes which means in some cases they are more than just little details about the note. I believe this mean we’d like to see them when previewing the note; or at least have the option to do that with a selector.
