I recently came across a very handy utility which installs a lot of small but much needed extras for Fedora.
EasyLife for Fedora allows users to setup Flash, Java and a range of codecs and tools to play just about any multimedia file. It also has options to set the sudo functionality for normal users.
The utility can be downloaded from http://easylifeproject.org/.
Install it as root and you choose what features you want to enable. Its as easy as that.
