Think about a dropdown defining the appearance of the component: Primary, Secondary.
Now, imagine, that RichText Editor is only relevant for the secondary appearance.
It would be great if we could hide (visually) RichText field when the primary appearance is set and/or show the field when the secondary appearance is chosen.
Much less clutter and distraction for the user.
(This idea comes from third-party solutions for custom fields in WordPress where conditional logic is a must-have feature. Maybe a good idea for a plugin rather than the core.)
