Comment 2 for bug 1792699

Well... no, because it doesn't let you select the user origin which has already been set. And you can't select e.g. any grid point, you can select only items and whatever are their center points.

Logically, if you think about the names of the dialogs, the functionality I miss belongs to the "Position Relative To" dialog. (Except that it wouldn't be "relative to reference *item*".) The old functionality should then be moved to that dialog.
