LibreOffice has page direction option on brochure printing when CTL is enabled (Tools - Option - Languages - check to CTL).
This option should be for Asian layout, too. We Japanese user want to use this option.
1. Yoko writes a tiny book on vertical text, and she wants to print on brochure printing.
2. John who is Japanese comic as known as manga artist. He wants to draw a manga on Draw. Most of Japanese comics are right to left direction (bound on the right-hand side) .
