I am fairly new to coding and just downloaded this theme. I wanted to link pages directly as opposed to having the drop down menu, which is what it seems like you are looking to do also.
For example, I wanted a link to the homepage, Here is how I edited the sidebar PHP file.
this is the original:
<!-- Pages -->
<li><a href="#"><?php echo NAV_PAGES_TITLE; ?></a>
<ul>
<li><a>"><?php echo NAV_HOME_TITLE; ?></a></li>
<?php wp_list_pages('title_li=&sort_column=menu_order'); ?>
</ul>
</li>
I edited it to look like this:
<!-- Home -->
<li><a href="https://www.thelinkyouwantgoeshere.com">
<?php echo NAV_HOME_TITLE; ?></a>
</li>
Thats its. Also note, in the translation php file you have a series of code under suckertree menu that looks like this:
// SUCKERTREE MENU
define('NAV_HOME_TITLE','Home');
define('NAV_PAGES_TITLE','Pages');
define('NAV_LATEST_POSTS_TITLE','Latest Posts');
define('NAV_CATEGORIES_TITLE','Categories');
define('NAV_ARCHIVES_TITLE','Archives');
define('NAV_FEEDS_TITLE','Feeds');
You can edit or make up new ones so that it corresponds with the code in the sidebar php file.
For example (from the sidebar php):
<?php echo NAV_HOME_TITLE; ?>
I added
define('NAV_HOME_TITLE','Home');
in the translation php file and then used it in the suckertree menu in the sidebar php file.
I hope my explanation was not too confusing and this helps with what you were looking to do.
