Annotation notes on a diagram had no styling of their own. They were drawn in the diagram's background color with the diagram's outline color and the generic text font, which made them blend into the canvas instead of standing out as a remark attached to a concept.

The diagram properties now offer two extra entries: a Notes color and an Annotation notes font. A note is drawn in the note color with the note font, and by default those are the familiar tooltip colors - a pale note with dark text - so notes read as stickers on the diagram without any setting up.

Notes already on a diagram follow the style: picking another note color or font recolors them right away, and a saved style carries both settings with it.

An annotation shown inside a concept follows the note font as well, but keeps the colors of the concept it is written on.
