On some sites it doesn't make sense for categories to be displayed alphabetically.
There is currently a very simple mod that allows site owners to order categories by category_id (see
Pligg wiki: Category Management). I am wondering if it makes sense to add this as an admin panel configuration setting so that libs/html1.php (which i am guessing is frequently updated) does not need to be modified and maintained when upgrading to future versions of Pligg.
Alphabetical order should still remain as the default setting because ordering the categories by id requires modifying the database records for each category which may be beyond the comfortable scope of some users.
