Great app! Far easier (for me at least) than Cmd-tabbing to switch apps. But it's not just an app switcher, it can also be used as a launcher for favourite apps. By default, TouchSwitcher adds all the apps that are in the dock. I removed a few by un-favouriting them (press and hold the app icon, then tap the star to un-favourite). I also added a few apps that aren't in my dock as favourites (launch the app, press and hold the app icon and tap the star, then quit and the app will remain visible in TouchSwitcher).
