Search for packages in Launchpad PPAs: a regular search which is faster, but doesn't display exact package matches and comes with less details and a deep search which displays exact package matches. In the search, you can also see if a PPA is already added on your system or not and if a package is already installed (and the installed version). You can perform the following actions on a PPA listed in the search results: add it, list packages in the PPA, open PPA in browser, download packages, install a package using the built-in installer (if the PPA is not already added, it will be added)
Update single PPAs - without running a full "apt-get update", which should be a lot faster (and especially useful for computers with slow Internet connections)
List packages in PPAs enabled on your computer
Edit PPA source file
Remove duplicate PPAs
Import all missing GPG keys
Fix GPG BADSIG errors
Backup an restore PPAs (automatically imports missing GPG keys)
Re-enable working PPAs after Ubuntu upgrade: when you upgrade to a newer Ubuntu release, the PPAs are disabled so using this feature, the PPAs that work with the new Ubuntu version you're using are re-enabled, leaving the others disabled
Update release name in working PPAs: somewhat similar to the feature above, this one is useful if you've backup up the PPAs in say Ubuntu Precise and restored them in Ubuntu Quantal (just an example) - in this case, using this feature you can replace "precise" in each PPA source with "quantal", but only for the PPAs that have packages for Quantal.
