Ususally where I lose my patience is trying to position/align an object. I think it would be helpfull that when you hover or click on a point in the visualizer, that it shows its coordinates, so you can just copy those.
@Jolien sorry for the delay. Indeed this is good point that we implement a back trace method to get feedback from the visualizer.
In the mean-time you can use the print() command to get attributes of an object.
If you have a script you can point me to those and I can create some demos for it.
Let me know.
Also check out Shape.align(…) for easy/easier alignments!
