Change swipe up home button shortcuts I have a Nexus 5 with ParanoidAndroid and I'd like to change that Google Now shortcut to lightbulb, how can I do it?
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.
