Currently it can be very confusing if the custom atoms labels are not displayed and you try to add some. Nothing happens (apparently).
If we add a custom atom label we should toggle the visualization of the custom atom labels for this specific molecule.
Not sure how to implement this. Any callback to know a custom atom label was added / modified / removed ?
@tpoisseau any suggestions ?
