Perhaps a slightly different arrangement would work more nicely. In
Opera 12, when cycling tabs via ctrl+tab brought a view not unlike
alt+tab in Xfce (especially similar to the list mode), the was an
optional preview window next to the list. The preview window was big
enough to be useful (see attached).

Xfwm4 may adopt a similar alt+tab layout, pretty much identical in
list mode, and with a preview on top of the horizontal icon list
otherwise. This would ensure that the previews are usable, although
you would only get one preview at a time when the window is selected
via <tab> or by hovering the mouse.

Do you think you know what math is?
Or what it means to be intelligent?
Think again:
