Kicker (KDE)
Kicker (also referred to as "KDE Panel") is the main panel used in KDE 3 and earlier, and also in the TDE desktop. Together with KDesktop, it forms the graphical shell. It can be customized by the user. By default, it has the K Menu, a Desktop Access button, a Home button, a Konqueror button, a Kontact button, and a Help button. It also has the Desktop Preview & Pager, the Taskbar, the System Tray, and the Clock. It was a core part of the KDE desktop, and as such, packaged as part of the kdebase module. Kicker was  also ported from Qt3 to Qt4. In KDE Software Compilation 4, Kicker, KDesktop, and SuperKaramba were replaced by KDE Plasma 4. The graphical shells KDE Plasma 4 and KDE Plasma 5 being widget engines of their own, SuperKaramba is no longer necessary and e.g. "Kicker" was re-implemented as such a desktop widget. Kicker is currently developed by the TDE developers for the Trinity Desktop Environment. Kicker can be launched separately in other windowing environments that lack a panel of their own, such as twm, and in case the twm menu lacks some of the commands that Kicker may have . This can be done by editing a codice_1 file, or from a terminal emulator: Applets. Kicker can embed various applets into itself. The included applets as of KDE 3.5 are:
