So it's workable now.
Just add this (as well as the abovementioned changes to .../English/common.php)
$visit_links['search_topics'] = '<span id="search_topics"'.(empty($visit_links) ? ' class="first-item"' : '').'><a href="'.forum_link($forum_url['search_user_topics'], $forum_user['id']).'"title="'.$lang_common['My topics title'].'">'.$lang_common['My topics'].'</a></span>';
to the header.php near or instead of:
$visit_links['unanswered'] = '<span id="visit-unanswered"'.(empty($visit_links) ? ' class="first-item"' : '').'><a href="'.forum_link($forum_url['search_unanswered']).'" title="'.$lang_common['Unanswered topics title'].'">'.$lang_common['Unanswered topics'].'</a></span>';
I would rather do it instead since too many links in the header may become garbled on smaller resolutions (laptops, old comps, etc), besides the forum's slogan is simplicity.
