The bar on the launcher that is docked at the bottom of the screen, that has 3/5/? icons on it, usually the middle button is the app drawer (but not necessarily).
The extra dock bar I was referring to... in ADW, if you go to
Menu> ADWSettings> UI Settings, and verify that "Dockbar" is checked (should be on by default), and then use it by going to
Menu> ADWSettings> General Behavior
and set swipe down actions to: "Open/close DockBar"...
Then from the home screen, if you swipe down over the dockbar, it will dissappear. MOST people just believe that the dockbar is hidden, but in fact, that blank space is a second dock bar, that you can drag apps to (up to 6, I believe (?))...
To get back to your other launcher, just swipe down over the dockbar again... REALLY convenient to have 11 icons right on the main screen, just on the dockbar.
Edit: Correction, holds a lot more than 6... just you swipe left and right to scroll over for more..

Very nice..
Pretty sure I'm going to go back to 3 home screens, pretty much just for widgets.
