Views are displayed in panes in the DataWindow editor window. Some views are stacked in a single pane. At the bottom of the pane there is a tab for each view in the stack. Clicking the tab for a view pops that view to the top of the stack.
The DataWindow editor has a default layout, but you can display the views you choose in as many panes as you want to and save the layouts you like to work with.
Each pane has:
A title bar you can display temporarily or permanently
A handle in the top-left corner you can use to drag the pane to a new location
Splitter bars between the pane and each adjacent pane
