Effect > Distort & Transform > Transform: Arrange duplicates above source
When you duplicate objects using Object > Transform commands the duplicate is arranged above the original object. If you use Effect > Distort & Transform > Transform to make multiple copies of an object the copies are arranged below the original object. This is wrong. The original should be the rearmost object and each copy should be arranged above.
I realize that correcting this behaviour (and there can be no doubt the current behaviour is wrong) can break the appearance of some files. So instead of just switching the behaviour add an option in the dialogue to place each copy either above or below the original. The default should be above.
