SUGGESTION: Anchor Points For Shape "Size" Property

The Problem

• In Shape Layers, the “Anchor Point” in the Shape Transform group only affects Scale and Rotation, but not Size.

• When animating the Size property (e.g., of a Rounded Rectangle), the shape grows or shrinks symmetrically from the center, regardless of where the anchor point is.

• This makes it impossible to do natural-looking directional growth (e.g., “expand downwards from the top edge”) unless you hack around it.

  

   

  
  
  Here's an example:

• I have a Rounded Rectangle.

• I move its Shape Transform anchor point to the top edge.

• If I animate Scale, it respects the anchor point, but the rectangle gets distorted (stretchy look) instead of staying proportional.

• If I animate Size, the proportions are preserved, but the anchor point is ignored — it always expands outward evenly in all directions.
  
  Why I think the anchor point should affect the "Size" property: 

• Motion designers often want shapes to “grow from” or “shrink into” a specific edge or corner (like buttons, UI panels, progress bars, apple style dynamic island animations, etc.)

• Right now, the only workaround is offsetting position keyframes to fake the directional growth, which is tedious and unintuitive.
  
  Breakdown/how this can be easily implemented:

• Make Size respect the Shape Transform Anchor Point.

• If a designer moves the anchor point inside the Shape Transform, Size animations should expand/contract relative to that anchor, not always from the center.

• This would unify behavior with Scale, Rotation, and Position — making the system more predictable and powerful.
