Removing the global applications menus
I don’t like how Unity removes the menu from the top of my windows and puts them in the topbar. Here’s a way to get your windows top menus back.
In a terminal enter:
sudo apt-get remove indicator-appmenu appmenu-gtk3 appmenu-gtk appmenu-qt firefox-globalmenu thunderbird-globalmenu
Then log out and log back in and the applications menus should be back on the applications windows.
Note 1: Applications menus will still merge into the Unity top bar when you maximize their windows.
Note 2: HUD won’t search menus after doing this.
