Auto vs. manual. Best practices, delays, angles, etc. A bit of this is in the eReader work, actually, so we've already thought it through as a team so that gives something to go off. Angle at which you commit to rotate, animate it possible, be fast, don't change context, but DO re-fit to screen, try to make notate buttons and locks an anti-pattern except for special cases. Fix the sense issue first.Also mention, maybe, flipping? These both are a good example of how gesture is doing specific good, outside of generic gesture. May be with mentioning in the Part Intro?
