How to change tab-window Z position, or hide behind the main window?

kitakoredaz

I often separate panes of daz studio,(mix shader or timeline etc) and set undockable ,so that I can open many tab as window,
and arrange them in monitor 2D space, but there seems no way to change z-layer position of each sub windows.

I expect, when I select DS main window, now the window turn active,
then these divided pane windows should be hidden behind the main ds window,,
but,, once I separate misshader tab, or others, these sub windows always cover ds main window,,

Is there setting option,,to change the behavor?:roll:

eg,, Now I open IE, Blender, and DS, then I select one aprication, the Active window must turn up in front of all.
