In the 3.x days of KDE, there were some wonderful applications. One of them I still admire, is kscope. Recently, I stumbled upon this blog entry and thought of sharing my living with kscope.
The move from KDE 3 to KDE 4 was a big one. During that move, the kscope author decided to port kscope to a Qt only application. That is what we have as the latest kscope, 1.9x version. But, on personal taste, it is not as good as the 1.6x series.
