Currently, Google primarily uses the HTML structure and especially headlines to structure the website. Unfortunately, Gamma's entire logic is hidden in DIVs and formatted using CSS. It looks good, but it's not readable by Google.
Of course, it would be best if the styling and the HTML markup could be set separately so that the following can be created.
Title -> Option H1
Heading 1 -> Option H2
Monster -> Option H2
Heading 3 -> Option H3
That would be the most flexible way to separate the layout and the semantic HTML markup or set them individually.
