Just a few days ago, Auxo developer Sentry posted a conceptual video detailing how quick app switching on iOS could work. He has now posted an additional video that streamlines the concept even further, and it is a big improvement over how the native iOS multitasking bar currently functions. It is highly possible that Sentry, as a jailbreak developer, could release this concept on Cydia as a full-out modification in the foreseeable future. Hit the break for the video.
