Please re-instate the Map window controls available in previous versions of MindManager

In previous versions of MindManager you could close the active Map by using the small close icon on the window controls as shown in the image below:

These controls are missing in MindManager 2016 and I am forever clicking the close icon and have MindManager itself close when all I want to do is close the active Map.

Is there a reason why this could not be re-instated in the next service pack or at least in MindManager 2017?

Regards
Nigel
