I think that by now everyone who touched KDE can pretty much figure out how to customize the appearence and shortcuts. Plenty of settings can be changed via kcontrol
. Numerous themes can be downloaded from sites like www.kde-look.org. All of these are pretty trivial.
There is more to customizing KDE though. Much more. KDE has a very modular block-type design. This is great because you can easily use these blocks to build something that you need and that noone has created yet or at least not shared in a way easily locatable. I am talking about kdialog
and kdcop
.
