Altering the Dock
I personally dislike the default Dock. It sits at the bottom of the screen, right where I need extra screen space for my work. It’s too big and it’s ugly. Fortunately, the System Preferences application provides a great starting place for customizing the Dock. Choose
→ Dock → Dock Preferences to get started. The Dock Preferences pane (Figure 1-14) lets you set the size, position, and other attributes of your Dock to better integrate it into your workflow.
Adjustable features in the Dock Preferences pane include:
