Action Launcher Pro: Drawers and Widgets
Action Launcher Pro hides your app drawer to the left of the screen. It can be accessed by swiping from the left edge of the screen to the right, or by tapping the circle icon in the top left-hand corner of your screen. Items are listed in alphabetical order, making them very easy to find.
To access widgets, just tap 'Widgets'. While TouchWiz only allows certain apps to be resized, Action Launcher Pro lets you change the size of all of them. The third screenshot in this slide shows the same widget in three different sizes. Some widgets adjust well and look good regardless of their size, while others simply aren't made to be manipulated.
More recently, Chris Lacy has introduced a Quickpage which provides access to a drawer from the right side of the screen no matter what app you are using.The Quickpage can be customised just like a home page, but its grid size is static.
