So I have a parent window (red) that has two child windows, and the another window (green) is beside the parent window.

What I want is that if I am in the 2nd child window in red and I do focus left, I want it to cycle back to 1st child, because what's happening is that it goes to green window, since it's on the left of 2nd child.

Is there a way to make the navigation of child windows stays under their parent window?

I hope this makes sense.
