Now version 7 which generates 1 .svg file per run which is an entry in Document History (Recent files).
This .svg can be opened using other programs or imported into GIMP.

Previously the script would generate multiple .svg (one for each time it strokes so) the .svg files are partial data and were removed.

Now you can generate the gradient path and use it in other programs (programs that use .svg files like Inkscape i guess I don't know I don't know too much about Inkscape).

Cheers.

Thanks man, too busy to play with gimp have to wait till weekend.
