Hiding admin toolbar and linking off of the site to the project page is counter intuitive

There doesn't currently seem to be a config option for that. Both hidding toolbar and linking logo to drupal.org is hardcoded.

It however can be fixed with a bit of custom code. Logo link is hardcoded in the page--mercury-editor template that can be overriden and showing admin toolbar is controlled by the `_hide_admin_toolbar` route option that can be altered → . I'm using following route subscriber to do that:

class MercuryEditorRouteSubscriber extends RouteSubscriberBase {
  /**
   * {@inheritdoc}
   */
  protected function alterRoutes(RouteCollection $collection): void {
    // Show admin navigation on Mercury Editor route.
    $mercuryEditorRoute = $collection->get('mercury_editor.editor');
    if ($mercuryEditorRoute !== NULL) {
      $mercuryEditorRoute->setOption('_hide_admin_toolbar', FALSE);
    }
  }

}

It works quite well for the new admin navigation → (combined with changes from https://www.drupal.org/project/mercury_editor/issues/3449328 ✨ Hide new drupal admin navigation on mercury editor routes Needs review ), not sure how it will look with other admin toolbars but it should make them show up.
