It would be cool if LiveCode could tap into underlying OS animation functions.
For example, at WWDC 2017 Apple showed how UI KIT can support interactive and interruptible animations.
These are very handy for doing smooth and interactive transitions.
LiveCoders are used to building things like transitions between screens.
But more and more OSes offer ever more sophisticated animations and transitions at the OS level. Users will expect the real things rather than facsimiles.
Admittedly LiveCode may have a difficult time supporting such native features, especially as OS vendors seek to differentiate themselves with unique features without direct correlates on other OSes.
