iPad Note Taking

Can someone please work on making Notability, or some equivalent notebook/note taking app or function accessible from the unlock screen. I still carry a pocket notepad and a pen, because opening my iPad, unlocking it, bringing up Notability, opening up a new note, and writing a note to myself takes so long I’ll forget why I did all that in the first place. Taking a note should be as easy as accessing your camera, or turning on the flashlight function.
