Go to Setup > App Settings > App Designer

This feature allows you to add additional items that will appear in the main menu within the app. To add a new menu item, click on Select an Item and choose the feature you would like to add from the drop down list.


Once you have made your selection, you can re-name the menu item and also move it to another position on the list.


When you are happy with your changes, click on Save Changes at the bottom of the screen.
