@Keith-Collyer said: For now, I don’t have Edge […]. In case anyone else is interested, you can try previewing plain-text wireloom files with this development build of Preview HTML. MS Edge is still required, since the wireloom JS library is only available as an EcmaScript module, which Internet Explorer doesn’t support.

I would say wireloom looks more like YAML, with its bash-style # comments and significant leading whitespace (note the syntax highlighting in the GIF illustration above).
