4.1 Uninstall Packages
To uninstall one or more packages switch to the status view and mark "Installed". Now you'll see all packages that are installed on your system - you can browse them or search one or more packages with the search function. In the search field you can enter a package name or search term.
If you found a package that you want do uninstall, click on the green checkbox and select "Mark for Removal" or "Mark for Complete Removal" from the context menu. The difference between the both options for uninstall is, that a complete removal will also delete the configuration files while the normal removal won't delete them. This can be useful if you want to keep your configurations for a package (you can install it again later and don't need to configure it a second time).
Afterwards the package is marked with a red cross.
To make the changes effective click on "Apply" in the upper menu bar and afterwards confirm your choice.
Now the uninstallation begins.

The packages you want to install will occasionally have dependencies - then a window will pop up and you have to confirm that you want to install the additional needed packages as well.
Afterwards the package and its dependences are marked with a yellow arrow. Dependencies are marked in green as well.
To make the changes effective, click on "Apply" in the upper menu bar and afterwards confirm your choice.
