To view the Dial Bar, Drawers or Dock, swipe the very bottom of the screen (where the Dial Bar is displayed) to the left or right to cycle through the Dial Bar, Drawers or Dock view.

What is the Dock?

The dxTop Dock is where you can add shortscuts or 1x1 widgets to the "dock" at the bottom of the screen.  You can bring up the menu by long pressing the menu button and bring up the System (2nd) tab by long pressing the back button.

What is the Dial Bar?

The dxTop Dial Bar is a launch bar that allows you to quick launch the core phone fucnctions, like contacts, messaging, browser, etc.  The left and right buttons are user definable, to change them, long press on the button.  You can also define the center Drawer to be the normal App drawer or the System drawer.

What are the Drawers?

dxTop's unique dual drawer view allows for more than just launching apps.  Sometimes called the tabs, the drawers have two functions.  The left drawer, know as the app drawer, is the traditional app launcher drawer (but dxTop allows you organize your apps in many advanced ways).  The right drawer, know as the system drawer, is an application manager that displays the most recently used applications and displays which apps and services are still running in memory.  The system drawer allows users to kill apps they don't want using up memory on their phone by either long pressing on the individual app/service or pressing menu to "Kill All" apps and services.
