Listaller frontends
Listaller frontends are - primarily - the existing PackageKit frontends like Apper or GNOME-PackageKit. But a special Listaller frontend is required if you want to have a nicer setup process and you want to make use of some Listaller-specific functions, for example installing into user's $HOME.
Also, Listaller frontends provide a very nice way to manage installed applications.

Because of the ongoing rewrite of Listaller, KDE frontends are not yet available, but they are @work.
