It would be nice to be able to vary the thickness of the tube while drawing out the tube with pen pressure.
It will save a lot of time manually adjusting every point afterwards to get multiple natural flows from thick to thin and vice versa
Would be handy for artistic/expressionistic lines. Hair, grass, tree branches etc.
Basicly just drawing 3D lines with pen pressure in 1 go.
Min/max strenght adjustable preferrably.
