CoW has now gained a new "module" -- cowident.
The image below shows what it does. When you run it, it will force you to select a window to then report properties on.
It's analogous to FvwmIdent from #fvwm3
Not the sexiest thing in the world, I know, but maybe useful both for those tweaking their config, and for diagnostic purposes.
That's why #FvwmIdent was created -- to allow for diagnostics.
