I found this via the MM mailing list - and looks great in the screenshot! Unfortunately, it doesn't seem to work with the latest MM version (Version 1.14 (5937)). Any chance you've updated it?

I get this message when trying to use it: "Unable to create window layout: Unable to create window using the “MmSeparatorView” view type. If you are using a custom layout then it needs to be updated to work with this release of MailMate."

UPDATE: I found some mailing list messages as recent as 2019, that this was now included in MM. But I don't see it in the included Layouts. Unless I'm just missing it, which is possible! ;-)

I have update on my laptop. Ping me tomorrow. Watching Denmark vs France in then finals…

Ping! :-)

see https://gist.github.com/maxandersen/40b70477ad8594565f24f9b7b45abf5d and let me know if that works.
