Hi all, I want to set up a layout that treats two matched windows as one, like always side-by-side. I also want to be able to switch the "master" layout, like: Tall .. ||| Mirror Tall .. ||| simpleTabbed and keep this pair of windows always together side-by-side in this layouts. Of course I will have other windows involved in this layouts and that's the point. I've tried sublayout but I found it to hard to set. Also tried ComboP combineTwoP, which comes close to what I want but has sad limitations like "reserving" the area to the 2nd layout and not being able to switch the ruling layout. Does it make sense or I'm wanting something too odd? Thanks, Henrique G. Abreu
