I am new to KDE and I have come to like the plasmoids on the Desktop. They can be used to display information (eg. Weather, Time, News) or can be used to carry out some tasks (upload images/text to web, check mail etc) easily.
Oxygen-transparent is a modification of KDE Oxygen-style to add cool transparency. It was supposed to be merged to KDE 4.6, but the idea has been dropped due to issues with the theme. However, it can be installed in KDE 4.5 and 4.6 currently. I am using KDE 4.5 in Fedora 14 and here is how I got it installed.
I have used Ubuntu Lucid since its early alpha stages to the final and then continued using it until lately. I am used to having title bar control buttons (i.e. maximize, minimize, close) on the left side of the window. I recently moved to Fedora 14 KDE Edition and was having problems with the control buttons. So, I moved them to the left. Here is how it is done.
I just installed Fedora 14 KDE Spin and like many other Linux distros, it does not play MP3, MPEG and several other formats by default. To enable playback of these proprietary formats, you must install non-free codecs. To get those, I installed the Livna and RPM Fusion repos by clicking the following links and opening each with KPackageKit:
RPM Fusion Free
RPM Fusion Non-Free
