General question or idea:
is there a way to draw in autofill/loop mode with the vector line-tool?
that's for creating closed shapes, maybe with a smoothing slider?
And even more important: do you see a way to integrate intelligent gradient fill for this function? Would be a KILLER feature. Settings: Smooth, Autoloop, Fill, Gradient
The idea is to make the gradient fill depending on where you start drawing your shape. Gradient fill always from color to transparency, with a slider for color intensity.
Normal vector fill (whatever setting) is just so 90'ies - having seen what YOU can do, it would be just great !!!
Please find my sample here:
