(i posted the same text under the script-topic too)
i am looking for a script that really would speedup my and many workflows. i can t write it. i m not able to do such a great job. maybe there is someone out there who can write it and who thinks the invested time has been worth it.
i like the sketchy stile with a quite lot of lines that are not welded. so i do a fast sketch with the freehand tool:

now it would be time for the new skript. i just describe the vision:
i press on a key (shortcut) or on a symbol and then the magic begins. the script creates a second layer, a special reference layer with the same points as in the original layer. in this layer all the points are connected (in a way i chose in the curvature-tool-settings). and the figure is filled with a color i chose (and i can change later with the select shape tool). it s just a "fill"-layer. if i would render just this layer i would not see any stroke-line. this layer is placed directly under the original layer.
(here i faded out the original layer)

so, by now there are 2 layers. the stroke layer and the fill-layer.

in my vision these layers work together like they were one and under the chair of the original layer. if i change one or more points of the original layer the equivalent points of the fill-layer are changed in the same way and same time. no matter if i change the points with the transform-points-tool or a bone or in an other way.
So we can transform the figure like we are all used to it with the diference that we transform one layer and the second layer, the fill-layer, is transformed at the same time by the programme .
in this way one can build up a figure in the sketchy-style really fast. respectively with...
- one original- and one fill-layer for the head
-one original- and one fill layer for the eyes
-one original- and one fill-layer for the hair...
...and so on.
