Please support vertical writing text (characters from top to bottom, lines right to left) which is common in the East Asian countries such as Japan, Taiwan and Korea.
Vertical text is the very important feature in the region and many people can't get away from Illustrator just because of it, even though we have been looking for Illustrator alternatives.
Apple used to support the feature on AppleWorks, but no longer since Pages was released and does not seem to have any plan to support in the future.
Once you implement vertical writing, you will gain significant share of the market for sure.
