I'm assuming you're using Addresses 1.7...
The easiest way to show all subcategories on the top page (instead of just the first 5) is to comment out line 59 in index.php. Currently it's:
$chcount++;
change it to:
// $chcount++;
This just prevents the loop counter from being incremented so that all subcategories are shown.
Alternative approach: If you just want to increase the number of subcategories shown, without including all of them, change the '5' in line 50 to the number of subcategories that you want to show. For example:
if ($chcount > 10) {
will show 10 subcategories instead of 5. Don't comment out line 59 if you use this approach.
