Hello Ignacio,
We do not think it makes sense adding all of this as settings as eventually you will have thousands of settings to show / hide items. Having said that, you can always customize the theme file in /components/com_easysocial/themes/wireframe/users/default/items.php and remove the codes below:
[gist]
<li data-breadcrumb=".">
<span class="t-text--muted">
<?php if ($user->getLastVisitDate() == '0000-00-00 00:00:00') { ?>
<?php echo JText::_('COM_EASYSOCIAL_USER_NEVER_LOGGED_IN'); ?>
<?php } else { ?>
<?php echo JText::sprintf('COM_EASYSOCIAL_LAST_LOGGED_IN', $user->getLastVisitDate('lapsed')); ?>
<?php } ?>
</span>
</li>
