“While Tweak-Center mockup was a brilliant idea that
stood out from the rest of the crowd, here is another very
interesting concept that demands your attention. USC Launchpad
Concept integrates Ubuntu Software Center with Launchpad and

hosted at Launchpad to its users.
“Ubuntu Software Center + Launchpad Mockup
“Thousands of Ubuntu/Linux software projects are hosted on
Canonical’s Launchpad service. So many of the PPAs for Ubuntu are
also located on Launchpad and it seems mad not to integrate this
into the Software Center. So much great software for Ubuntu can be
found on Launchpad but it can’t be installed on Ubuntu easily.”
