Inkscape, but nothing unusual (at least for Inkscape, and no where near as much crap as Inkscape adds if you let it save as an Inkscape file rather than plain svg!) and nothing that Fritzing objects to.
Yes, but as you note I was moving the motor not the interface board and that indeed does not work. I agree if I move the interface board then it connects correctly (and I think that is a Fritzing bug as it should be symmetrical)
I would agree, but it was there, so I corrected it. Even if it doesn’t make sense I often add pcb with at least header pins so if someone wants to include it in a pcb they can (presumably by connecting wires from the connectors.) If I’m lazy I suppress pcb view.
