Just the usual stuff. I finally got around to changing Pidgin's tray icons, and I added a little gradient to the keyboard layout icons, so they look like Faenza's tray icons... I also tried different compositors (xcompmgr, compton, cairo-compmgr), but cairo-compmgr was really unstable, compton doesn't like docky, and xcompmgr doesn't like XFCE panel. So I'm stuck with XFWM's compositing and no panel shadow.
