Dear Xara,
How about moving on from the text format and embracing a basic graphics format?
Although X3D was initially created primarily for text, many use it for manipulating their own custom shapes.
Having the limiting DTP type controls over non text shapes can be tedious. Greater positioning flexibility would be most welcome. Nothing complex, I just want to move away from the typewriter constraints. At the same time I have no interest nor patience in learning how to use dedicated 3D software.

Regards
Anas
