I've personally switched to Nova, but I doubt I'll be able to convince my father to do the same.
But I'm not talking about the bar, I'm talking about shortcuts.
EDIT: I found the answer. 4.1 and higher seems to combine the widgets and shortcuts in the widget section of the app drawer. (Since I use Nova, I never had to look in there for them)
