imo there just need to be a few more default easing functions, the standard ones aren't quite natural enough. There must be a standard curve equivalent to the "human pushing/pulling an object from A->B" function that would actually look natural. EaseIn/EaseOut/etc is never quite it; human motion has a bit of higher-order feedback used to regulate it. Maybe to do with the combination of: all the motion happens via muscular springs, plus, there's a well-trained system that regulates the motion to minimize inefficient use of energy. Whether I jerk suddenly and then stop it, or move it slowly so it smoothly decelerates to the final point, it never looks as mechanical as the stuff you see in code.

And the parameters should be tied to reality as well like object weight, surface tension, hand strength, ...?

If you want? I don't care about the parameters, I just think the default functions should include some more sensible options that look less mechanical.
