Here is what I ended up using in init.php:

PHP Code:

#
# Show All Mod (Based on mod by Westin Shafer for Beach Bums Inc.)
#
if ($show = $_GET['show']){
    $config['Appearance']['products_per_page'] = $show;
    $smarty->assign('show',$show);
        
}
# End Show All 


I removed the {if $total_pages gt 2} condition in subcategories.tpl so navigation.tpl would always load. Then I put this at the end of navigation.tpl, after the last {/if}:

{* View All mod *}
{if $usertype eq 'C' && $products && $smarty.server.PHP_SELF ne '/manufacturers.php' && $smarty.server.PHP_SELF ne '/orders.php' }

{if $show ne ''}
<a href="{$navigation_script}">{$lng.lbl_View_paged}</a>
{elseif $total_pages gt 2}
<p class="NavigationTitle"><a href="{$navigation_script}&amp;show={$current_category.product_count}">{$lng.lbl_View_all} {$current_category.product_count} {$lng.lbl_products|lower}</a></p>
{else}
<span class="NavigationTitle">{$current_category.product_count} {$lng.lbl_products}</span>
{/if}

{else}
<p />
{/if}
{* End View All *}

Eventually, I would like to add a field where the customer can set a number of items to display on each page, but I couldn't figure out the session variables right away, and it's not high priority.
