Ubuntu Linux only: Ubuntu Tweak is a small customization tool that gives you a single access point to some of the interface and file browsing options tucked away in Ubuntu’s advanced preferences or text configuration files. Along with a few of the more common Compiz Fusion and interface preferences, Ubuntu Tweak lets you enable useful functions for CD burning, easily enable and change splash screens, make advanced power management changes, and even lock down certain tools for security reasons. Experienced users may know how to change a lot of things in this app, but for new installs, and new users, it’s a time saver. Ubuntu Tweak is a free download for Ubuntu Linux systems.
