One Switch is a really good app, and I will not remember to use this app generally because it's in my menu bar, and I only need to switch the actions I need to use, like hide desktop apps, keep awake, etc. one thing I think one switch has down for this app which I think anyone who gives the reviews should know, which is how many times you been switch using One Switch, whether it's the shortcut you set or dropdown menu from the menu bar, you will be surprised, I know for a lot of people, it's hard remembering shortcuts, which I be honest with you, I remember most, but never remember FCPX shortcuts, so I would say $4.99 is a pretty good price I would pay.
