Launchpad PPA, (Personal Packages Archive) is a common way to install apps that are not available in Ubuntu default repositories. For beginners, it’s a little complicated to manage the PPAs via the default “Software & Updates” utility. So here’s a handy tool called Y PPA Manager.
Y PPA Manager is a graphical tool developed by Webupd8 Team. With it, you can easily add, remove, purge PPAs, list packages and install them.

Add a PPA box will do the same thing as below terminal command does:
sudo add-apt-repository ppa:ubuntuhandbook1/apps

Manage PPAs window lists enabed PPAs. With it you can:
Remove a PPA will disable the ppa repository. The installed packages from this ppa are still there.
Purge a PPA will disable the ppa as well as downgrade installed packages to default version available in Ubuntu default repositories.
Update package lists after adding or removing a ppa repository.
Edit source allows you edit the config file with text editor.
Lists packages will display available packages in selected ppa.

Y PPA Manager also allows to search PPA, install a package with a given name, backup /restore repositories, and even more.
