window managers with maximize-vertical?

["Monique Y. Herman" <spam@bounceswoosh.org>]

It seems to me that, long ago in a galaxy far, far away, I had a window
manager that supported maximize-vertical (as opposed to maximizing in
both directions).

Anyone using a window manager right now that does this?  Preferably one
that interacts well with gnome.
