I tried :
`$fav_screen_function = $bp->bp_options_nav;
bp_core_remove_subnav_item(‘activity’,’favorites’);
bp_core_new_nav_item( array(
‘name’ => ‘Favoris’,
‘slug’ => ‘favorites’,
‘position’ => 20,
‘show_for_displayed_user’ => false,
‘screen_function’ => $fav_screen_function,
‘item_css_id’ => ‘favoris’
));`
The remove subnav is ok, and the new nav Favoris is created, but it links to a page where the subnav is the nav again, and it looks quite strange… I guess I should create a subnav.
