The Ubuntu Software Center is probably one of the most actively developed feature for Maverick. It now has an updated look with features apps and new apps. It has also got plugin supports and some form of social media integration.
Well, it continues its improvement and now it will handle the installation of .deb file, instead of the old Gdebi. Now, when you click on a .deb file, the Ubuntu Software Center will open.
This is a very good move from Canonical and it will streamline the installation of applications in Ubuntu. However, a concern that some people have been raising is that it would make a third-party .deb file seem like it is from the repository. In the current implementation, there is a warning, but perhaps it would be a good idea to make it more visually distinct – say, a different color background, as people are suggesting.
In a related news, the Ubuntu Software Center has got its first paid application. The application is Fluendo DVD Player and they are selling it for $24.95.
