SSD (Sawfish Session Dialog) is a small and flexible wrapper for session commands. It is intended to be used with Sawfish, but does not require it. It can be configured to use any command for logout, reboot, shutdown, suspend, hibernate, and lock actions. Preset command definitions are available for: KDE4, GNOME2, XFCE4, MATE, and Razor-Qt. It is part of Sawfish-Extras (currently there's only SSD, but more is planned).
Design Center is a Web application that allows users to change the colour of different layers in a photo. In a photo of a bedroom, there could be layers for the walls, the ceiling, and for the floor. The application lets users change the colour of each and see how a new paint job would look. If used on a furniture store's Web site, different layers could be used for beds, chairs, lampshades, etc. to allow customisation by users.
