Layout Override Files that gives you control over the display of modules or components. Override files are placed in special folders and can be used in place of the standard layout files. Unlike Template Overrides, which override layout files of the same name, Layout Overrides are additional layout files that give you more options and control.
Alternative Menu item Alternative Menu Items are used and work the same way as standard menu items. Since they are already based on customised layouts, template overrides do not apply to alternative menu items.
Editor A user level on a Joomla site that by default can access only the front end. Editors have privileges to post and edit content, but no permission for publishing content.
