giving more vertical space in an interface

I'm sorry if my comment was interpreted as saying “look how wrong you are”; that wasn't my intent.

I'm excited that there are common languages that are legible in only a small amount of horizontal space, because it does allow putting some interface elements at the side of the screen or of a window when native English-speaking interface designers wouldn't usually think of that option. Icons are one tool that can help in allowing what might be a horizontal interface element (titles of windows/tabs/..., buttons, menus) to fit in a vertical space; using vertical text is another, and it's important to remember that vertically-oriented text (whether with glyph rotation or not) can work well in some languages better than in english. I thought a "one-line" response would make an impression that might inspire interface designers reading the thread, and might serve to remind them of this possibility for their creations.
