I've got too many assignments to list and too few assigned for the Activator-based tweaks that I have installed.
But some of my majors…
Home button exits apps and then locks/unlocks. Short hold on power button calls up the Flashlight and turns it off when it's on.
I have an Activator-based tweak that triggers DND when I flip the mute switch. DND off when the mute is off and on when the mute is on.
Really, too many to list.
