Some devices will not have a traditional homescreen dock area and when Z Launcher is installed, the dock area of Z Launcher will be blank. You can drag and drop any icon on the homescreen or Apps drawer to this dock area using Z Launcher.. Simply long press on any app icon until it becomes drag-able. Drag it to the dock area of the homescreen and drop it. You can have four docked apps, two on either side of the Apps drawer button located bottom-center of the Z Launcher homescreen.
