Karel, No need for me to look at it as I am not a developer. I am just trying to help find an existing method that can do what you want, and maybe clarify the desired function. Perhaps Steffan or Hans will like to see the video.
If you have explored the function of ellipses and lines then you know what can be done and what cannot. Now you have to try to make a sufficient case to get the enhancement coded - or learn to do that yourself. If you are the only person who ever wanted this, then you may find that developing it yourself is best.
