I actually went and asked the author if he could code them for me and he got back to me almost immediately. Here's the info:
Do this to the [current_action]
if (in_array($context['current_action'], array('search', 'admin', 'calendar', 'profile', 'mlist', 'register', 'login', 'help', 'pm', 'arcade', 'shop')))
And add this for your links for the shop and arcade:
// Show the [arcade] button.
echo '
<li', $current_action == 'arcade' ? ' id="active"' : '', '><a href="', $scripturl, '?action=arcade">Arcade</a></li>';
// Show the [shop] button.
echo '
<li', $current_action == 'shop' ? ' id="active"' : '', '><a href="', $scripturl, '?action=shop">Shop</a></li>';
Obviously if you don't have the arcade or shop, you can easily see now how to edit it. Credit goes to the author, crip.
And does anyone know why in my profile (and in posts) my post count is "I am a geek?"
Profile view:
Posts: I am a geek!! (35,025.501 per day)
I don't believe I (or anyone else) could get 35,025.501 posts per day...
