This option should contain a comma separated list of container names. Each container contains a specified list of tool bar controls (buttons, separators, selection lists). The controls for each container are specified in settings named "theme_advanced_container_<container_name>". This option can only be used when theme is set to "advanced" and when theme_advanced_layout_manager is set to the value "RowLayout".
