[xmonad] Displaying the window name

[Bruce Stephens]

Is there some unobtrusive way to see window names?

I'm imagining something like the workspace name displaying that (I
think) WindowMaker has: as you change to a workspace, its name appears
in the centre and fairly quickly fades.

I know xmonad has various tabbing feature, but after years of using
window managers with lots of decoration I'm rather enjoying having
almost none, so using one of those would be a regression.

I only rarely want to know a window's name, and on those occasions
using xprop is adequate, but it would be nice to have something more
convenient, something that displays the window name in the top left
hand corner of the window momentarily when focus changes to it, say.

(I guess I could build something myself either using an xmonad hook,
or using an external application and a dynamic log, but my guess is
there's some program already written that'll do it, or someone else
will have coded it already, and probably better than I can do it.)
