This version provides many minor enhancements, file name changes, and better themes, but above all, themes are now split into two kinds: "look themes" that change the visual aspects of the window manager, and "feel themes" that change the key bindings, the way windows are raised, etc. That way, you can change the colors of the windows while keeping your preferred focus and window raise methods.
This release cleans up the file layout, includes the menu and key bindings configuration in separate files, and keeps themes in a common directory (like the wallpaper images).
