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. Other features: * Handling of all hidden preferences * Fully internationalized interface using gettext * Detection of running Claws Mail * Support for alternate configuration directories
