Grease Pencil feature request: Curve Tool/Node Tool (Blender 2.90)

Hello guys. I would like to propose a feature that would allow the user to handle the curves or strokes similar to how affinity designer implements the node tool.

I truly believe the functionalities of these vector editing softwares can be very useful in blender's 3d modelling and especially grease pencil. These tools can potentially make the workflow much faster, easier, and more organic. The smooth workflow it offers will make grease pencil sketching feel more primitive/natural.

Here is the node tool and pen tool used in affinity designer:

Thanks.
