If you are constantly confused over the command line, and wanted to look for an easy way to tweak your Ubuntu, then Ubuntu Tweak is definitely the application for you.

Ubuntu Tweak allows you to tweak many desktop and system settings without going to the terminal. It provides a single access point for you to change some of the hidden Ubuntu settings that are not available during your default desktop installation.

UT is currently designed for Ubuntu GNOME desktop only.
