                'url' => qa_path_html('ask', (qa_using_categories() && strlen($lastcategoryid)) ? array('cat' => $lastcategoryid) : null),

        /**/
 

Answer 1

With qa-theme.php this can be done by:

 

            // change navigation: bring "ask" to front
            $hash = $this->content['navigation']['main'];
            $hash = array('ask' => $hash['ask']) + $hash;
            $this->content['navigation']['main'] = $hash;

            // additional: remove tags from menu
            unset($this->content['navigation']['main']['tag']);

Answer 2

As of 1.8.6, the order can be changed in: /qa-include/app/page.php

Move this block:

_{// Only the 'level' permission error prevents the menu option being shown - others reported on /qa-include/pages/ask.php}

_{if (qa_opt('nav_ask') && qa_user_maximum_permit_error('permit_post_q') != 'level') {}

_{$qa_content['navigation']['main']['ask'] = array(}

_{'url' => qa_path_html('ask', (qa_using_categories() && strlen($lastcategoryid)) ? array('cat' => $lastcategoryid) : null),}

_{'label' => qa_lang_html('main/nav_ask'),}

_);

_}

above 

_{if (qa_opt('nav_activity')) {....}
