Luban not showing Position of Z-Seam

Is there an option in Luban to show the exact position of the Z-seam as in Cura?

I can set the preference of the position for the layerchange but the preview doesnt show where the Z seam is located. Cura highlights it with white dots, but in Luban the box to show the starting point seems to be missing.

Am I missing something here? Is the option hidden somewhere else?

Greetings, David

Am I really the only one who is annoyed by that little detail?

How are you guys checking where the Z-seam is positioned?
