Markdown -> HTML issues (list levels and theming)

Hi Benny, I can't really catch up with MailMate's improvements, trying them out, but here's one I was wondering now for quite a while.

The documentation, or what I find using Google, doesn't really help me how outgoing mails are formatted and rendered in the preview pane. I understand that you use (or used?) sundown to convert Markdown to HTML - but how to control it (and e.g. add more layers for bullet points - which is what I'd like most to e.g. structure meeting notes in a mindmap-like fashion [besides some smaller headings]) is still a mystery to me.

I actually thought maybe it's the sundown utility that needs to be extended as it's not seen any updates since many years. Or is there maybe something else where I could get some control over my formatting and this bullet point thingy?

Ah, an example would be of course good, so here's one (watch especially out for 'Level 3'):

Hi

# Header 1

## Header 2
* Level 1
  * Level 2
    * Level 3
* Level 1 again

Text

Is there some CSS e.g. applied from somewhere for outgoing mails, or is there something only used for rendering in the preview pane?

Thanks,
