Thank you Arlex.
I have found the file and was able to amend the Home button to the website index.php 
 
As to ADDING IN new links, it appears to be more complex. This is a current link for POLLS...
<?php if ($this->config->get('polls.enabled')) { ?>
				<li class="<?php echo $view == 'polls' ? 'is-active' : '';?>">
					<a href="<?php echo ESR::polls();?>" class="es-navbar__footer-link">
						<i class="fa fa-bar-chart"></i>
						<span>
							<?php echo JText::_('COM_EASYSOCIAL_TOOLBAR_POLLS');?>
						</span>
					</a>
				</li>
				<?php } ?>
What would the code be for a simple link to 
/social/ page (keeping the pipe "|" between links)?
