Reusable components are great… but once a component is reusable, it cannot be re-used as the basis for some other new component. For example, creating a modal template with a set of containers, blocks, buttons, etc cannot be used as a template for other modals… because one cannot put new components inside of a reusable component without affecting all instances of that reusable component. So to make a new modal with different content, we have to re-create the modal template from scratch (since there is no copy/paste for components across pages). So, a feature which which would be super useful:
An option to take the instance of a reusable component and make it not be a reusable component anymore. That is to say, break it up again into it’s individual components, doing the opposite of what the “make reusable” button does.
