Do you know a plugin to modify the BuddyBar (BuddyPress nav)

Sorry
My Keyboard was in bug…
So I make a function to do that :

<?php 
add_action( 'bp_setup_nav', 'test_board', 100 );

function test_board() {
    global $bp;

    bp_core_new_nav_item( array(
        'name' => 'Tutoriel',
        'slug' => 'buddy-tutorial',
        'screen_function' => 'bpis_profile',
        'position' => 10
        )
    );
}

function bpis_profile () {
    echo do_shortcode('[bpis_tags]');
    echo do_shortcode('[bpis_images]');
}
?>

But I don’t know the file than i have to copy/paste in my childtheme and how i have to rename it to edit my pages.

Hello,

IS a function.php to add a new item tab item in the BuddyPress User Nav.
when i click on this part i go on :
http://www.zikrea.com/membres/wilfried/my-slug-name

So i need to edit a page my-slug-name with the URL http://www.zikrea.com/membres/wilfried/my-slug-name.

But i don’t know how do that.
( I have to make a page in my Dashboard, and change the URL directly form the dashbaord. )

Or I have to copy paste a file like page.php put it in my child theme and rename it : page-myslug-name.php and edit it. ?

Or maybe i have to put buddypress.php in my child theme and rename it buddypress/my-slug-name ?
