Improved focus detection: In previous version th calibration window was turned into the current one. At all two translations were used causing a jitter. Now the current view is translated into the calibration windows by one step increasing the quality of the prediction. Reworked detection of pitch/sector/scroll events: Sector and scroll uses pitch angles to calculate the view to show. Movment detection uses movment, which may also be out of focus for a short time. To improve all detections these two use cases are now handled individual. Sector and scroll have increased action angle in case yaw and roll stay stable.
