+Technically the page properties are the same as the form displaying the page

+Plugin options: Settings at plugin level
+========================================
+
+The plugins of many extensions come with settings inside the content
+element representing the plugin. These are commonly labeled "Plugin options"
+
+Depending on their permissions, editors may be able to edit the settings of
+a plugin.
+
+In general, plugin-specific settings are evaluated in the following order:
+
+#.  `Site settings <https://docs.typo3.org/permalink/t3coreapi:config-overview-backend-site>`_
+#.  `TypoScript <https://docs.typo3.org/permalink/t3coreapi:extbase-typoscript-configuration-plugin>`_
+#.  Settings made inside the plugin's content element
+
+The settings of a plugin are commonly found in a tab called "Plugin" and
+a section called "Plugin Options". Extension authors are, however, free to
+chose different labels.
+
+..  figure:: /Images/ManualScreenshots/Backend/PluginOptions.png
+    :alt: Plugin Options of the Frontend login plugin
+
+    Example: Plugin options of the Frontend login plugin
+
+Extension authors can use `FlexForms <https://docs.typo3.org/permalink/t3coreapi:flexforms>`_
+or `TCA <https://docs.typo3.org/permalink/t3tca:start>`_ to configure
+plugin options that can be set in the content element of the plugin.

+TYPO3 can handle multiple sites within one installation. For example, one
+TYPO3 installation might contain a company's web site and a few landing pages
+for special products and events.
+
+Even if your TYPO3 installation only contains one site, this site needs to
+be configured. This includes the domain used to reach the site,
+language related configuration, error handling (for example a custom 404 page)
+and the inclusion of "Sets" of settings.
