Hi Martin, something like rounded end caps may happen eventually in a sort of offline render method where it would calculate an image but which may take a while longer to generate than the regular real-time viewport display. It's a big focus for the regular display to do its job quickly and that tends to put some limits on what I can handle there.

But most likely I will be trying to focus on generating a hidden-line output to Illustrator first before stuff like that happens directly in MoI.
