Just to touch on this - the subject did come up on IRC. It shouldn't be
difficult to separate the focus and layout again by adding a layout list
while keeping the focus zipper. It should even be simpler for some tasks
such as adding new windows to the master position. But it is extra
book-keeping and it seems most users prefer focus order = layout order
for tiling mode.
