Literally, Figma, Framer, Sketch, InVision Studio and whole lots of others have this.

It lets you resize a Group or Frame, without messing it's child layers Constraints, Positions and Responsive Design. Kind of like an override for resizing Frames / Groups.

Just implement it just like them : Cmd / Ctrl + Resize on any direction.

Basically for quickly masking child layers inside a Group, without really needing a Mask layer (which sometimes doesn't work to be inside, if your Group is with Stacks)

Also to make the Prototyping on the Canvas much neater, for Drag Groups that goes beyond the boundaries of the Artboard. Look at the screenshot for reference
