Or stay with xfwm4 and write a script using wmctrl. Sometimes xdotool
might be helpful, too.

An example, the terminal is active and I activated the Claws window:

[rocketmouse at archlinux ~]$ wmctrl -lx
0x00c00003 -1 panel.fbpanel         archlinux panel
0x0080001d -1 panel.lxpanel         archlinux panel

You could assign a script to a shortcut. Pushing the shortcut a script
could activate one window after the other, e.g. using a
"for"-loop getting the windows from a list. The list likely could be
provided by $(wmctrl -lx | cut -d" " -f4 | grep -v '^$') , but you
should test, if this always works. If you want it more advanced, the
script needs to check the position of the active window and those of
the windows surrounding the active window. This is what you want and
it's possible to do this, too.

Off-topic:

An example how I use wmctrl:

If I push Ctrl+7 my WM (openbox without a desktop environment) runs
win75   and if I push Ctrl+Alt+7 it runs   win75 -   , win75 is the
following script, that resize the active window:

[rocketmouse at archlinux ~]$ cat /usr/local/bin/win75 
#!/bin/bash
eval $(xdotool getwindowgeometry --shell $(xdotool getactivewindow))
X_FIX=$(grep X_FIX ~/.rocketmouse/win75/config | cut -d"=" -f2)
Y_FIX=$(grep Y_FIX ~/.rocketmouse/win75/config | cut -d"=" -f2)
((XX=X-X_FIX))
((YY=Y-Y_FIX))
WIDTH=$(calc "int($WIDTH*0.75)")
case $1 in
  "") HEIGHT=$(calc "int($HEIGHT*0.75)");;
esac
echo "x:$X-$X_FIX=$XX/y:$Y-$Y_FIX=$YY"
wmctrl -i -r $WINDOW -b remove,maximized_vert,maximized_horz
wmctrl -i -r $WINDOW -e "0,$XX,$YY,$WIDTH,$HEIGHT"
eval $(xdotool getwindowgeometry --shell $(xdotool getactivewindow))
echo "x:$X-$X_FIX=$XX/y:$Y-$Y_FIX=$YY"
exit

To avoid that the resized windows are moving, a config is required,
providing an offset that can be found by trial and error:

[rocketmouse at archlinux ~]$ cat ~/.rocketmouse/win75/config
X_FIX=4
Y_FIX=50
