This node group controls points, edges, faces, splines, instances, and face corners, with customizable falloff functions (Linear, Sinusoidal, Power, Exponential, Circular, Bounce, Elastic, Smoother Step, StepLinear) animating from 0 to 1. It also offers easing options (Ease In, Ease Out, Ease In/Out) for smooth transitions and deformations.
The Interpolation node is from a free resource I found on YouTube by Higgsas.
