For people coming from a traditional animation background, setting easing with words is very confusing.
I love the easing editor, but am confused as to why it isn't available everywhere you can set easing.
I also think that a modified version of the easing editor would be great for animations that contain multiple keyframes. This is also a traditional 2D/3D animation workflow, and would greatly help us envision what is happening as we move through multiple keyframes. This would simply be a wider version of the current editor, with additional bezier handles being added for each additional keyframe on the timeline.
