Hi there, I wonder if there is a way to change the ruler size and location. I know there are options for thin and thick, and different colour but I wonder are there more options for customization?

Many things are possible, but most things that aren’t currently exposed would require C++ coding to change. If you are interested in that, you could [start here](https://github.com/Slicer/Slicer/blob/ff1ba1679ae98a6a2e669d79dde1ad8620b60c04/Libs/MRML/DisplayableManager/vtkMRMLRulerDisplayableManager.h#L31).
