It would be really nice to be able to refresh content in content studio after a save when we have node api listeners running.
Sometimes the content we are handling in xp is just a reference to an external resource with metadata stored in xp. In these cases we are fetching metadata/content from an external service and storing it in the xp content object. The only way to refresh the content in content studio at the moment is to add some page reloading javascript to the rendered part in edit mode.
