Since I switched to a window tiler, I never need to move windows unless I'm doing something complex in GIMP. I'm using pytyle2 (you can probably find something better) and mostly all I use is alt-c to rotate the windows, alt-h for "higher" and alt-l for "lower" and that's it. Now I rarely, rarely ever resize or click-drag a window.

This works so well I totally stopped using window decoration. Having the extra pixels on my laptop is nice! Install the "Classic Compact" add-on for Firefox to free up even more pixels.
