The possible uses for PagePacker would keep me busy for ages. I’ve already set up a day-planner example (with larger type and lines, to accommodate my advanced age) and a booklet of prayers that I want to keep conveniently at hand. I can imagine using it for class hand-outs. And so on.
I wish I felt venturesome enough to try working directly from Multivalent with the directions that Mac OS X Hints gives, but PagePacker looks quite sufficient for me.
