Customizing the thumbnail preview globally

[chetbaker]

Hi there,

There's a thread on the Hedgedoc forums regarding this.

Even thought there is a way to change it through frontmatter metadata, there is no way to do it globally.

One of the maintainers is suggesting to edit the file under public/default.md in the installation directory. Is there any way we can have some customization of this at Cloudron?

Thanks!
