The Workspace Preview System (WPS) is a set of Drupal modules that enables site builders and editors to send content through an editorial workflow and preview it in the context of the live site. It facilitates the creation and management of workspaces, which can be full copies, filtered views, or empty, and integrates with workbench moderation for workflow states. WPS is part of a larger initiative to improve Drupal's content workflow and preview capabilities, with future enhancements planned for content moderation and deployment.
