Custom breadcrumb seperator 5.0 problem

Hello,

This is a great plugin, using it for a while now. Only one question.

With the new update my current function does not work::

function breadcrumbs ( ) {
	global $bcn_admin;
	if($bcn_admin !== null)
	{
		//Grab the current settings from the db
		$bcn_admin->breadcrumb_trail->opt = wp_parse_args(get_option('bcn_options'));
		$bcn_admin->breadcrumb_trail->opt['hseparator'] = '<div class="sep"></div>';
		//Generate the breadcrumb trail
		$bcn_admin->breadcrumb_trail->fill();
		return $bcn_admin->breadcrumb_trail->display(false, true, false);
	}
}

In this function i used to edit the hseparator to change it to a div (for a image).
Works great in the previous version. Only in 5.0 the code has changed. After a quick look i found out that this would work.

function breadcrumbs ( ) {
	global $breadcrumb_navxt;
	if($breadcrumb_navxt !== null)
	{
		//Grab the current settings from the db
		$breadcrumb_navxt->breadcrumb_trail->opt = wp_parse_args(get_option('bcn_options'));
		$breadcrumb_navxt->breadcrumb_trail->opt['hseparator'] = '<div class="sep"></div>';
		//Generate the breadcrumb trail
		$breadcrumb_navxt->breadcrumb_trail->fill();
		return $breadcrumb_navxt->breadcrumb_trail->display(false, true, false);
	}
}

Ony breadcrumb_trail is a protected class. Solved the problem Dirty by editing the protected to public. Only that is not the good solution.

On the page https://mtekk.us/code/breadcrumb-navxt/breadcrumb-navxt-doc/2/ it says things about bcn_breadcrumb_trail_object && bcn_settings_init. Is it possible to create the same output like above with the new filter code?
I am still trying to fund the right solution, but help is welcome.
