And (at least in Xfce) dragging to a corner makes it fill that quarter of the screen. Really nice for building tri-window layouts where you need one tall and two short windows, which is how I typically arrange my windows when I use a tiling WM anyway, especially when programming: tall window for code, top short for Magit, bottom short for DirEd (if I have a high enough resolution, I might sometimes turn that into three smalls - Magit + DirEd + a REPL - which Xfce doesn't seem to support, unfortunately).
