Tellico has some additional configuration options that are not visible in the Configuration Dialog. They are not important enough to warrant cluttering the dialog with more settings, but as they represent options which may appeal to various users, the application does read them from the configuration file.

The settings for Tellico are saved in a file in the user's home folder, namely $KDEHOME/share/config/tellicorc. Within that file, settings are put in groups, which appear with bracketed names, such as [General Options]. To add a setting to the General Options group, find the line in the settings file with that group name. If it does not appear, then create it yourself by adding a line saying [General Options]. Then, the setting can be added underneath the group name.
