Concept seems good, but I don't see the red "H#" indicator, just the coloured background, and I don't see any explanation in the extensions notes that might explain why, or how to enable it.

Also, it says "differentiation of h1 - h6 tags by different colors", but there is no explanation of what colour is for which tag.

And what exactly does "day" mean in "h6 Highlight day" and "Display which day is currently being output"?

nothing to say :)))))
