Let's say you've got a few dozen checkboxes and associated labels
(that the development team insists is the method they're going with
despite any more elegant proposals). They're ordered alphabetically
in three columns.
Are people more likely to want to scan for the word they want by
looking across then down, or down and then across?
They're currently across then down (which, hello, English words do
that), but it looks funny to me. Maybe it has something to do with
the spacing.
