Actually your picking at something that could in fact be better. $db->query adds something over mysql_query (even if it's just OR die(mysql_error()); ) It's still something, since $db->num_rows adds nothing to mysql_num_rows() All you're doing is calling a class function to call a php function what's the point? I could be wrong not looked at v2's class in some time, however I do believe nothing is added.
As for the player + developer thing he is right, as long as it works, and is relatively fast for slow connection users they won't care.
As for tabbing get an IDE and it's done automatically for you. :whistling:
