In developing for mobile, I found that iTween just wasn't fast enough. In converting to LeanTween I not only removed most of the herky-jerky from my game, I also got a full 20FPS increase in frame rate!
These are the actions I made for my project. They're just the basics, but should be usable for many situations. Included are move, scale, rotate, alpha, pause, resume, and cancel.
If you find a bug or have any feedback, please post here or send me a private message.
Enjoy!
