Apple’s release of an AirPort Utility app for iOS 5 lets you leave the desktop version behind for most base station configuration tasks.

Move the Dock Quickly
You may find it convenient to move the position of the Dock when working in certain programs or with certain files. Rather than choosing a different position from the Dock preferences pane or using a submenu in the Apple menu's Dock submenu, you can move your Dock to a different screen edge merely by Shift-dragging the separator that divides the application and document sections.
