There are some areas, which need refinement:
- apps using more than three fingers won't work, as the multitouch gestures have priority. The only time I have noticed this was while playing Fruit Ninja in Zen mode, where I tend to use my whole hand.
- graphically it should be improved. When trying to swap apps to the left, from an app, which is furthest left, it stretches the app creating a very unprofessionally looking distortion.
- Performance wise does it need some improvements. When switching apps quickly, audio playing can stutter.
