Aren't there other tools that already offer copy and pasting ease data? Yes, but ARC takes into account the keyframe values and maintains relative direction so curves are accurate regardless of value changes. Watch the video "What's new in ARC 1.5 for more examples of optimizations in the copy/paste feature.
