Viewing the Menu Structure as a Tree
In the System Management application, the menu structure can also be viewed as a tree that contains the same functions as the menu bar at the top. The tree is displayed in a dockable pane that you can re-size or drag to another location. You can double-click a menu item to start the related function. The most recently accessed function is highlighted.
If you do not want the tree menu to open automatically, clear the setting Extra > User Interface > Preferences > Show tree menu when opening System Management application.
You can manually open or close the tree menu pane by selecting View > Show/Hide Treemenu.
