When creating a landing page, once initialized, the Studio tool bar shows the option to Delete or Save draft under the Publish action button.
Those should be implemented following regular eZ Platform content repository features:
- save draft saves the underlying content object without publishing it, keeping it open as a draft.
- delete just delete the draft.
After Save draft, the user should remain in the editor.
After Deleting the draft, the user should go back to the parent page in the site, in view mode.
Delete should have a modal dialog asking for confirmation.
