Similarly to the pages, patterns and templates pages in the site editor, we should explore how we can leverage the same DataViews UIs, frame, editor, navigation... to power the Posts section of WP-Admin as part of the Admin redesign project.

There are a lot of challenges here:

• Reusing the "pages" dataviews without duplicating all the code.
• Reusing the site editor shell, navigation menus and routing logic
• Generating forms for categories and tags creation and modification without necessarily creating custom code DataForm component #59745
• Extensibility DataViews and DataForm: Extensibility #61084
• Backward compatibility
• Transition

There's a lot to cover and a lot of uncertainties, for these reasons, I'm proposing that we start a new experimental page in the Gutenberg plugin, where we explore a new page that could serve as a playground to explore these ideas and address all the blockers.

Task list:

• Bootstrap a site-editor like shell Bootstrap the dashboard layout #62409
• Add the "posts" dataviews page. (@ntsekouras)
• Add the "categories" dataviews page.
• Add the "tags" dataviews page.
• Leverage DataViews forms to implement "Add new category" and "Add new tag" (and edit forms as well)
