Allow adding class to shapes

I would like to be able to assign specific behaviour to shapes. For example making specific shapes editbale. I know there's an editable field in shapes[] but that is a bit clunky (the user has to select the shape and then move it which doesn't always work very well).

I would like to be able assign a class name to shapes such that I can set specific css properties per shape. Is there a reason why a class/id can't be assigned to shapes? Could this be something that could be added?

Inizia tracciando come viene renderizzato shapes[] e in che modo il campo modificabile esistente influisce sull’interazione con le forme. Definisci il comportamento previsto di class/id e l’ambito CSS per ogni forma, quindi verifica che lo stile specifico della forma e la modifica funzionino senza compromettere il comportamento esistente delle forme.
