I've been using it since it came out. Before that, I used a NextStep theme for FVWM.
I'm dependent on WindowShade and wouldn't want to use a window manager without it.
I have the Window List menu pinned below the dock on the right side of the screen, from where it can pop out to full width if the mouse pointer touches the screen edge. I much prefer that over a "task bar" that doesn't show full titles but takes up a lot of space. (and no, I don't use other icons intended for the purpose)
I used to have my own patch with a few graphical tweaks but stopped compiling from source a long time ago.
