hey again, if people land here:
You can add a condition to this function in the slidebar.php (around line 240) of the main folder (the plug-in folder, you can access it throught FTP):
function output_slidebar(){
if( apply_filters('ns_slidebar_do_output',true) && (is_page('projects') || is_post_type('jetpack-portfolio'))){
include( apply_filters('ns_slidebar_template', plugin_dir_path(__FILE__).'templates/slidebar.php' ) );
}
}
