On the screen you can configure different "workspaces" which store how the various windows are displayed. This allows you to quickly recall different setups. Workspaces are stored and recalled from the touch buttons to the left of the menu buttons, or may be stored to any grey button on the console.
You can also create a Set List which will automatically recall a workspace layout for each song.
Pressing View/Open takes you into the View menu. From here you can set up what is shown on the screen(s).
Window Options allows you to reposition and resize windows.
Open Workspace Window gives a list on the softkeys of all the possible windows, allowing you to open the one you need.
