wishlist: show workspace in window list

hi, when you "hide" a window, it can be difficult to
find again thorugh the window list if you have a lot of
windows. as i discovered when i accidentally hid a
window just now. it would be great to show in the
window list:

a) which workspace each window is in

b) whether a window is hidden (e.g. by dimming the
icon)

thanks for icewm, i switched to it after windowmaker
crashed too many times. icewm is rock solid so far!

cheers,
m.
