funny, i just checked and the launcher you can't disable, but the google search you can. the bar disapears, but then its just blank up there, trying to move an app doesn't work since its the trash can lol.
disable apps, is settings, apps, all apps tab at the top, find the app you want, something like a verizon app. select it. you will see an option to disable it.
been playing with adw for a bit. and i can't quite get the folders to set up like i like them in the stock launcher. but i really like having a app draw that scrolls right. so torn. but will play with it more.
