I've now implemented the option of cloning instead of duplicating an object and all objects are now placed at the position of the original.
The placement of duplicates (not clones!) of _groups_ of objects after the transformation is not yet corrected for as that requires quite extensive adjustments which I didn't bother to figure out yet. As a workaround one could clone the object and break the link after the transformation, but I don't know if that is possible via an extension. I probably won't have enough time to figure this out in the near future so if you don't find any bugs (*fingers crossed*) I'd consider the extension "done".
