Since I seem to be getting in some edit wars, rather than continue with that, I wanna make my position clear.
Walls of text are ugly. They are a pain to look at, they are difficult to read, and they totally break up the flow of the story.
So please. When you're dealing with a block of text that takes up more than 1/3rd of the screen, don't use the "extend" modifier; break it up into paragraphs. It's much more appealing to the reader.
