I’m a teacher, and I use address labels to modify playing cards to use in classroom games. At the moment, LibreOffice only has the option to use the sheets in portrait orientation (as far as I can see) meaning the individual labels and landscape. In order to use them in portrait (to match the playing cards’ orientation), I have to manually copy the widths, margins etc into custom labels, transposing width with height, horizontal with vertical. A single portrait/lanscape switch in the new… labels dialog would make life much easier.
