Also works on iPhone 6s. It feels a lot snappier. Even though I have Pythonista on my phone, I have never used it for other than testing. But when you are coding who needs animations with the programming interface.
Can also confirm, if you do a hard shutdown of Pythonista, on relaunch everything is back to original. That's why I have put mine in the pythonista_startup.py (1.6 only)
