[IxDA Discuss] Fitts Law fits

[Jennifer Berk]

It sounds as though your concerns are about vertical space, with your
Items ending up too close together but not wanting to make them taller
for fear of hurting scannability.  A tree might not actually be the
most effective way of displaying the hierarchy of the information.

Are you able to use your horizontal space more effectively?  For
instance, you could make each Category the heading of a column, with
the Subcategories and Items displayed in tree form within.  Then it's
more possible to make the Items larger (taller) without feeling like
your page is ten feet long.
