I suggest to add the following function to selects.php and to privde an option in the admin panel to choose if the tags page is sorting by Popularity or by Alphabet:
function qa_db_alphabetic_tags_selectspec($start, $count=null)
{
$count=isset($count) ? $count : QA_DB_RETRIEVE_TAGS;
return array(
'columns' => array('word', 'tagcount'),
'source' => '^words JOIN (SELECT wordid FROM ^words WHERE tagcount>0 ORDER BY word ASC LIMIT #,#) y ON ^words.wordid=y.wordid',
'arguments' => array($start, $count),
'arraykey' => 'word',
'arrayvalue' => 'tagcount',
'sortdesc' => 'tagcount',
);
}
Or probably better: Modify function qa_db_popular_tags_selectspec($start, $count=null) and let the option switch between:
tagcount DESC
or
word ASC
see red spot!
