Editing Spiro spline is not a fun experience we could improve it by : * [ ] hide original path * [ ] hide bezeier handels {width=636 height=359} * [ ] allow only two types of nodes * [ ] circle for curved point * [ ] diamant for share point * [ ] editing shape by draging on new path (it could be implented tw ways clicink and draging would automaticaly added new curve point that you draging OR you would start dradging closes point sith offset ) * [ ] allow adding new point by doublclciking on spyro spline (not original spline)
