This also works for me as well. I use a physical logbook at work (some customers don't allow unauthorised electronics). Actions that come my way get marked with a circle. When I get some keyboard time I try to execute the action immediately or add it to an electronic TODO list, and in either case put a big X in the circle.
It is indeed simple and effective and doesn't require any tooling.
