Get the phpMyAdmin's Visual Query Designer

Step 1) open phpMyAdmin/config.inc.php and modify the below lines of code.

/* change this info to whatever user has read-only access to the "mysql/user" and "mysql/db" tables */         
    $cfg['Servers'][$i]['controluser']   = 'root'; //this is the default user for MAMP's mysql
    $cfg['Servers'][$i]['controlpass']   = 'root'; //this is the default password for MAMP's mysql

/* this information needs to line up with the database we're about to create so don't edit it unless you plan on editing the SQL we're about to run */
    $cfg['Servers'][$i]['pmadb'] = 'phpmyadmin'; 
    $cfg['Servers'][$i]['bookmarktable'] = 'pma__bookmark';
    $cfg['Servers'][$i]['relation'] = 'pma__relation';
    $cfg['Servers'][$i]['table_info'] = 'pma__table_info';
    $cfg['Servers'][$i]['table_coords'] = 'pma__table_coords';
    $cfg['Servers'][$i]['pdf_pages'] = 'pma__pdf_pages';
    $cfg['Servers'][$i]['column_info'] = 'pma__column_info';
    $cfg['Servers'][$i]['history'] = 'pma__history';
    $cfg['Servers'][$i]['table_uiprefs'] = 'pma__table_uiprefs';
    $cfg['Servers'][$i]['tracking'] = 'pma__tracking';
    $cfg['Servers'][$i]['designer_coords'] = 'pma__designer_coords';
    $cfg['Servers'][$i]['userconfig'] = 'pma__userconfig';


Step 2)    phpMyAdmin installs with the SQL we need to generate the database that the Designer relies on. We just need to locate the script. In 4.0.7 the file location is phpMyAdmin/examples/create_tables.sql. Alternatively, you can copy/download this from phpMyAdmin's github.
Once you locate the file, either import the file or copy/paste it into a SQL window and execute in phpMyAdmin.
Now, everything should be configured properly. We need to clear cookies and restart the browser.
When you open phpMyAdmin back up, navigate to a specific table and in the tabs you should see Designer tab.
