This is a simple tool that allows you to search for PPAs and install them without hitting the terminal. It also allows you to manage (add/remove/purge) your existing PPAs with a few clicks.
Open a terminal (hopefully this will be the last time you install PPA via the terminal) and type:
sudo add-apt-repository ppa:webupd8team/y-ppa-manager sudo apt-get update sudo apt-get install y-ppa-manager
Once installed, go to “Applications -> System Tools -> Y PPA Manager“.
