Appearance (Preference) customization of the look of Inline Annotations

I am thinking that Scrivener’s “Inline Annotations” function would be perfect if one could adjust Inline Annotation presentation style and color in the “Appearance” pane of Scrivener Preferences (as well as a global affordance to hide and show inline annotations) .

As they are currently presented, they are visually jarring and distracting.
