@imgel I wouldn’t consider #e16 a DE (still count?); but using that, I prefer having a frame-only window decoration. I use a simple #xdotool line in my #conkyrc to display the currently focused window.

${exec 'xdotool getactivewindow getwindowname'}

I’ve also used a combination of xdotool, randr, and eesh in the past to do tiling and arrangement.
