Except for native transitions (iPhone: curl up/down, flip right/left; Android: wink), are additional windows for animation are required? (one for each view?)
The KS "view animation" animates a window, not a view. Other discussions on related topic suggest the same thing. I understand that windows are "lightweight," but this does represent a major difference in transitioning between views/windows. This is especially true when sliding text views left/right (where you need to move both left & right sides to prevent damage to the contents).
Also interested in this answer. (Be great if there was a "follow" button on this forum).
I think animation is not required. You can just open a window without any animation.
Views are added to a window, if I am not wrong, so they are children of windows.
