      Comparing with scrolling on the other platforms (like iOS and Android), current defaults for QScroller overshoots extremely and scrolls with too much velocity. Properties provided below (taken from http://www.qtcentre.org/threads/57352-QScroller-speed-and-touch-screen) resembles other platforms. I think these properties deserves to be defaults compared to the current defaults.

      prop.setScrollMetric(QScrollerProperties::AxisLockThreshold, 0.66);
prop.setScrollMetric(QScrollerProperties::ScrollingCurve, QEasingCurve(QEasingCurve::OutExpo));
prop.setScrollMetric(QScrollerProperties::DecelerationFactor, 0.05);
prop.setScrollMetric(QScrollerProperties::MaximumVelocity, 0.635);
prop.setScrollMetric(QScrollerProperties::OvershootDragResistanceFactor, 0.33);
prop.setScrollMetric(QScrollerProperties::OvershootScrollDistanceFactor, 0.33);
prop.setScrollMetric(QScrollerProperties::SnapPositionRatio, 0.93);
prop.setScrollMetric(QScrollerProperties::DragStartDistance, 0.001);
