The view menu lets you set how many toolbar/utility windows are visible on the screen at one time.
The visibility of the toolbar/utility windows can be set
individually or by using 'view schematic' and 'view all' check buttons.
View all sets all the view options so that main toolbar,
minor
toolbar and utilities are visible while View schematic does the
opposite.
Note: All menus are still accessible when only the schematic
is displayed by using the pop up menu system : click and release the
right mouse button within the schematic window.
