The kdeaddons package contains several plugins for Konqueror. Despite their small size, they provide additional functions and ease the use of some of the functions Konqueror already contains, by making them more accessible.
More information on the use of Konqueror and it's built in functionality, can be found in the Kicker handbook.
This is a list of the standard configuration modules provided by the KDE addons package. Please note that there may be many more modules on your system if you have installed additional software.
