Meanwhile, could you please answer a quick question:
Does macOS builds support non-native tool-bar?

(info "(emacs) Tool Bars") contains this explanation:

     NS builds consider the tool bar to be a window decoration, and
  therefore do not display it when a window is undecorated.  *Note
  (elisp)Frame Parameters::.  On macOS the tool bar is hidden when the
  frame is put into fullscreen, but can be displayed by moving the mouse
  pointer to the top of the screen.

Does this mean that NS builds implement only external tool-bar?
This might imply the need to use an external tab-bar as well.
