Rounded Squares/shapes manipulator

Hi All,

I imagine this is quite a big request but I was wondering if it would be possible to implement a feature of rounding squares or shapes like in illustrator.

This would be incredibly handy for making limbs of characters but also for many things when it comes to designing.

This would invaluable for working on commercial projects as the style of the rounded shape is used a lot in the illustrator/aftereffects pipeline and would likely open up toon boom to be used in those productions.
