Please pardon my newbness, but I have a question about the KDE Control Center. I was wondering how to add new stuff to the control center (r they modules?); like a menu to configure my graphics card, and other useful things.

Using Suse, there were many useful extras in the control center. If it is possible, is it difficult to do, and where would I find them?

Thank you for helping a newcomer into the linux community!
