Clawsker is an applet to edit Claws Mail's hidden preferences.

Claws Mail has a high number of configurable options and, in order to keep the
binary small and fast, some of these preferences which are not widely used are
not provided with a graphical interface for inspection and/or modification.

Users wanting to edit such preferences had to face editing the configuration
text files directly, now it is possible with a convenient GTK2 interface using
Clawsker.
