There are two quick ideas I can think of, both very similar:

1) Create a version of your layout augmented with X.L.SimpleDecoration.  When
you switch to this layout, tabs displaying the window titles are shown above
each window.  Then you can switch back to the original layout and the tabs
disappear again.

2) The "problem" with (1) is that the windows are resized to make room for the
tabs.  An alternative would be to use X.L.DwmStyle instead, which displays the
window title on top of the window in the top-right corner.  The caveat here is
that the window title of the focused iwindow is not displayed.
