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 to do so with a convenient GTK2 interface using Clawsker. Requires GTK+2 bindings for Perl (perl-gtk2) available from SlackBuilds.org.
