Customizing virtual home button's app launcher I currently acquired a Motorola G and I'm wishing to add another application to the pop menu that appears when press-holding the home button besides the one that calls the search engine. I'm currently using Nova Launcher but I couldn't find any information in system configurations or Nova configurations.
You can use SwipeUp Utility to change the behaviour of the search action (swiping the home button) to launch a different app or shortcut.

I've contributed to this app (I helped the author fix a bug) but I've no financial interest in it.
