The current, Television and Persistent Playlists categories can also be manipulated by editing their XML storage. Of course one can do that when KMPlayer is not running and editing the various files in ~/.kde/share/apps/kmplayer/, but also in the application itself. Simply click on a category label, then choose View and next Edit mode. You can also click on a child branch and will then see only the XML contents of the branch.

After you have edited some XML, click on the Sync with playlist and either deselect the Edit mode item or click on another catergory.

Because of the lazyness of KMPlayer's author(s), some features can only be enabled by editing the XML .
