One thing i can’t get used to on Unity is that the global menu is located in the top panel. I am used to having the menu in the window from an application/folder/file. I did some searching and here is a way to remove the global menu and to enable the classic application menu. You can enable the classic application menu by removing the global menu. If you remove the global menu from the top panel the classic application menu will be enabled and it will be shown in the window from an open application/folder/file.
To remove the global menu open a terminal window (press Ctrl+Alt+T) and copy+paste the following lines:
sudo apt-get remove appmenu-gtk3 appmenu-gtk appmenu-qt
When the global menu is removed close the terminal window and restart your system.
If you want change back to the global menu open a terminal and copy+paste the following line:
sudo apt-get install appmenu-gtk3 appmenu-gtk appmenu-qt
When the global menu is installed you can close the terminal window and restart your system.
