i have shortcut for xfce4-terminal.
If no window has focus, it gets openened on top,
if a window has focus, it gets opened below that window.
I looked through the settings but found no possibility to autoraise new non-focus windows from the current workspace.
From beta3 chnage log:
- Avoid placing unfocused windows on top of the current focused window when not
focusing new windows (Bug #4795).
