How can I always show the close, minimise & maximise buttons into their own windows?

Solution 1:

This command brings menus and controls to their own windows:

sudo apt-get remove indicator-appmenu

This moves the controls into the window, but only when the window is restored. When maximised, the controls go back at the top, but that's OK because it's maximised anyway.

Removing the menu entirely (same answer):

  • How do I enable or disable the global application menu?
