This is a very minor bug; I noticed a duplicate line has worked it's way into config.sample.inc.php on both phpMyAdmin-3.5.0-english and phpMyAdmin-3.5.1-english:
$ cat phpMyAdmin-3.5.1-english/config.sample.inc.php |grep table_ui
// $cfg['Servers'][$i]['table_uiprefs'] = 'pma_table_uiprefs';
// $cfg['Servers'][$i]['table_uiprefs'] = 'pma_table_uiprefs';
Not a big deal, obviously..thanks to everyone's help in making phpMyAdmin an awesome piece of software.
