Request for feathering a mask or a shape

Not sure where to suggest or request a feature for Animate.. 

But one of the most essential tools in Illustrator and After Effects is the ability to feather a shape or a mask..

I really hope this feature is included in a new release of Animate. Would be a great program, if you could just feather a mask or a shape.  Trying to replicate this feature with a gradient with opacity is awful.

Please Adobe, include a mask feather and shape feather feature in future releases!!
