Colorize favorite annotations

[Chardonneaur]

Hi team, If we import a lot of annotations, it becomes difficult to identify which one are important. It would be great to colorize the annotations which are marked as favorites. Like this it will be easy to identify on a graph which one we need to take attention to.

For completeness: you can actually colorise favourite notes, but it's still not easy to read. I doubt it's WCAG compliant at the moment
