3. To configure the Appearance, celect Appearance and then one of the following:
   - Automatic detects the appropriate setting based on existing system or browser settings.
   - Light Mode renders the user interface using the standard color scheme.
   - Dark Mode renders the user interface using an inverted color scheme, applying light-colored text, icons and graphical user interface elements on a darker background.
4. To configure Preferences, select Preferences. In the Preferences dialog, edit the following:

   - Default Schema - Specifies the default schema used for data browsing, application creation, and SQL script execution. When using workspaces that have more than one schema available, this schema is the default for creating applications, performing SQL queries, and so on. This feature does not control security, only the user's preference.

   - Default Date Format - Specify the default Oracle date format for the user. This option controls the default date format within SQL Workshop.
   - Unicode CSV Downloads - Specify whether to provide SQL Workshop CSV downloads in Unicode. This does only affect SQL Workshop and not custom applications.
   - Run application in new window - Specify how APEX manages windows or tabs when running applications from App Builder when using Mozilla Firefox and Microsoft Internet Explorer. This setting has no effect when using other browsers, such as Google Chrome and Apple Safari.

     If set to On, the default, browser preferences are ignored and a new window always opens. If set to Off, the runtime application opens in a new window or tab based on Browser preferences. Mozilla Firefox and Microsoft Internet Explorer generally do not set focus to another tab in the same window, except when that tab is first launched.

   - Use single window to run all applications - Specify whether different applications reuse the same application runtime window or tab.

     If set to On, applications run from the App Builder reuse the window or tab used for running the previous application. If set to Off, applications you run display in its own window or tab.

5. Click Apply Changes.
