I have to agree with Markles in that I don't like to see changes to a template being reverted because they made one page look bad, when hundreds of others look better with the standardized templates.  As far as them needing the Show/Hide option, most of the standard navigation templates use this option now.  In addition, these templates may be small, but there are articles with lots of small nav boxes at the bottom, and their total sizes can add up to be quite large. -
