Ok after venturing a bit into the functions.php code i finally found the code responsible for tabs. Unfortunately i’m not experienced in PHP, but i assume this line will put out the content.
$out .= '[raw]<div class="pane">[/raw]' . do_shortcode($content) .'</div>';
What i was looking for is basically a next and previous button (button name is preferrably the same as the next tab’s name) placed directly under the current tab-content which (like a book) gets you to the top of the next tab, thus creating a flow for the reader.
I wanted to get this in as a lot of people kinda miss out that the article continues after reading the first tab.
