Shortcuts are expected to be as good as their namesake. Maybe it speaks to my diminishing cerebral power, or all of those years of college and screen staring finally taking it's toll on my learning abilities, but I have more recently found that anything more than one or two "custom" strokes, swipes, or other actions in order to shortcut to an app that I want or need is too much for me to learn, and quite frankly, not a true SHORT CUT.
