Appearance Tool
The Appearance tool is available by default and allows users to change the look and behavior of their Unity desktop. It opens to the Look tab (Figure 5-7) and allows you to change the background, theme, and Launcher icon size. The Behavior tab (Figure 5-8) allows you to change autohiding of the Launcher, the reveal location (where you need to put your mouse for the Launcher to reappear), and the reappear sensitivity levels. It also allows you to enable Workspaces as well as add a Show Desktop icon to the Launcher.
