The seasoned Fedora users may skip this article as this is targeted at those who wants to flirt with Fedora before falling in love with it. Fedora's default add/remove software tool is decent but is extremely frustrating with new users. One may find it easier to use terminal to install applications than from the add/remove tool.
The reason is the tool is not very efficient in finding the desired application or package. If you open add/remove tool and look for gnome tweak tool it will be a challenge to find the right package buried in the list of packages. In addition add/remove is also slow. The solution of this problem is Yumex or Yum Extender, which in my opinion is cousin on Synaptic Package Manager.
Run the following command in terminal to installed Yumex.
su -c 'yum install yumex'
Once Yumex is installed you will be able to search and install needed applications and packages with greater ease.
