Any progress about this topic?
Just came back to this thread while searching for "highlight"

Meanwhile I'm using Markdown for everyday notes (outside MSP) and really like it.
One more thought regarding Markdown vs. braces:
Markdown is designed to stay useful and readable when it is not supported at all, whereas the braces syntax e.g. {highlight: xxx} causes the highlighted text to disappear in case the current application doesn't support it (as most chordpro apps).
