I prefer gnome-terminal so I installed it and removed pantheon-terminal :
sudo apt-get install gnome-terminal
sudo apt-get purge pantheon-terminal
You can also use Software Center for these actions.
After installation gnome-terminal did not appear in slingshot-launcher....
Open a New Window As Administrator :
Navigate to /usr/share/applications and rightclick Terminal and open with Scratch :
Remove the two lines starting with OnlyShowIn ( or comment them with a # sign, the symbol # signifies a comment to be ignored when it is the first character on a line ).
To add the option Gnome-Terminal Here in the right click menu in Files :
Open a New Window As Administrator as done above and navigate to /usr/share/contractor and Create New File ( name it gnome-terminal.contract ), containing the following lines :
Description=Open in a terminal
To make the menu in gnome-terminal invisible we need to install gconf-editor :
sudo apt-get install gconf-editor
Applications > Configuration Editor > apps > gnome-terminal >profiles > Default > uncheck default_show_menubar
To make the menu visible temporarily just press F10.
