It's unbelievable that you still can't vertically align your content in Pages. Insult to injury, OS-X prints 4x6 Word docs as solid black pictures. Sad.
It's so frequently necessary to center your simple text content vertically on a page, yet Pages can't do it. Nor can Open Office Text Documents. Word does it quite easily. Word Perfect did it in 1985. (Yes NINETEEN EIGHTY.) I think it's because these programs are based in XML - ?? I recall learning how to code XHTML and there being no way to vertically align content other than using tables, which is really, really, really stupid. Can't put enough "reallys" in there. Now, all of a sudden, OS-X Yosemite 10.10, when printing my 4"x6" landscape index card notes created in Word, prints a solid black "photo" instead of my content. I'm going back to a typewriter I think. Worked for 100 years, where modern software works for maybe 2 weeks, if it works at all.
