Storyline Player Menu - minimize navigation menu

Hi Everybody,

I have been searching the forum for a possibility to toggle the navigation menu on/off. 

So, what I would like to have, is a minimize/maximize button for the menu in the player.

I found this string but these solutions don't work for me. Therefore, I am wondering if anyone knows a solution or if anyone knows if a request has been submitted for that already?

Thanks again.

Regards,

Chris Smit
