On forms shapes, the checkbox - I'd love a setting to show as enabled/disabled. When 'disabled' both the fill of the checkbox and the checkmark should be gray. When 'enabled' the fill on the checkbox should be white and the checkmark is black. Other objects I can reflect as being disabled through shading and color (gray it out), but visually showing the four scenarios of a checkbox is tricky in current state (checked-enabled, checked-disabled, unchecked-enabled, checked-enabled).
Checkbox show as enabled or disabled
