Brushing with metaballs [proposal]

I propose a tool within metaballs similar to brush tools.

It would allow user to create 'brush' metaball in space with LEFT MOUSE click instead duplicating it with shift+d. That way it will be faster to create mesh.

Also metaballs could have mirror modifier preview.

Brush tools for metaballs would be :

-create/brush metaball with left mouse

-curve guide brush : metaballs will follow curve stroke with brush

-negative/difference bool brush ( negative influence metaball ) metaballs will repel each other with this brush

-planar brush for adjusting to one plane

Tool could be in left side shelf where is metaball panel
