When prototyping interactive component animations, we import from Figma e.g. expanded and collapsed state and use one of the two to create the start and finish positions of the component's child elements.
It would be amazing (and seemingly easy feature) if we could select a layer, hit a 'Keyframe' button and it will create all the appropriate Responses automatically: Move, Rotation, Scale.
Then, we would move layers around, hit "Add another Keyframe" and it would add the new Move, Rotation and Scale responses.
We would have to prepare the conditions between the two or more states, but it would save a lot of time trying to assign Xs, and Ys for each move response manually.
And i think it would open doors for another feature like Component States.
