Summary
Illustrate the careful engineering of navpop;
 * 1) popup is clearly distinguished from the item, in a space-efficient way
 * 2) position of the popup is anchored to the link, and invoked by hovering over the link
 * 3) content is sorted by time, each time entry distinguished by alternating light/dark bands
 * 4) content is laid out in columns as well
 * 5) content cells are judiciously abbreviated, in a space-efficient way
