I'm adding this to the to-do list!
(When Series 3 is released, I will base the new PnP file on the DIAD version; updating Series 1 and 2 will have to come after that, unfortunately.)
Regarding cutting marks: If I recall correctly, the cut lines get cut off when printing on a normal printer because there's not enough extra margin(?) I had them on some older PnP versions, but removed them for some reason.
