Is there a window manager for power users that don't like tiling window managers? Half my windows are too big to be tiled (browser, IDE, Inkscape, GIMP, etc.) Plus, I have the desktop background for a reason: I want to see it. I don't want an austere screen paved over with windows like a city with no grass. I like my large windows to not be completely maximized, so I have some empty space. I like having my windows a little disorderly, not quite properly aligned, for the same reason Japanese Go boards are a little too small for 19 stones to fit: nature doesn't create orderly grids.
I really miss sawfish, though. I like Alt-Tab to activate the actual window instead of a little a row of icons (it'd be even cooler if it would turn the inactive windows greyscale). I like being able to turn off window decorations per app. Sticky windows don't flicker when you change desktops, like they do on Lion. And, of course, a config file for the things you always want in the same place.
