If you use sawfish you might find my modules useful:

* dmg-gpsy: it makes it easy to use grow/pack/shrink/yank window

* dmg-iswitch-window: similar to the way to switch buffers with emacs. It provides a list of the focusable windows currently in the window manager and allows you to use a regular expression to narrow the list, and select one. Way faster window switching than any other method in any window manager. Variants allow switching by class, within class, and all windows.

* dmg-quadrants: a very basic and rough set of tiling functions for your screeen.

* dmg-after-rotate: provides support for autorotation. Very handy if you use sawfish with a tablet.
