Configuration tweaker for Claws Mail
Clawsker is an applet to edit the so called Claws Mail hidden preferences. . Claws Mail is a fast, lightweight and feature-rich MUA with a high number of configurable options. To keep the binary small and fast some of these preferences which not widely used are not provided with a graphical interface for inspection and/or modification. . Users wanting to edit such preferences had to face raw edition of their configuration files, now you can do it with a convenient GTK+2 interface using Clawsker.
