I just discovered LeechTunes which let's you control music plyback on your iPhone with gestures such as swipe left to skip to next track, etc. It seems that this would be great for when listening to the iPod in the car whiile driving cause it's easier and safer to simply swipe than to visually hunt for and tap the next track button in the iPod app. However, I am not impressed with LeechTunes user interface and it lacks a scrub bar. so I am curious if there is an alternative. Does anyone know of any other iPhone apps that let you control iPod playback with gestures?
