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+3 interface using Clawsker. In addition to hidden preferences, windows positions and/or sizes and keyboard shortcuts can be edited.

Should be mentioned at least as a recommended component when downloading Claws Mail. Happy to have found it for tweaks such as this one: the default sorting in the Sent folder is, basically, by your own email address. You can swith this on the GUI tab inside Clawsker so the default sorting happens by the recipients address. One vital setting, in my opinion, is the option to have the FROM column show the sender's address (or name and address) instead of the default, which is ONLY the name. This default setting is surprising, because you have a higher level of security when you can see the sender address (also), not just the name, which is much easier to spoof than a whole email address. There are many more options waiting to be explored in Clawsker, and they are all explained when mouse-hovering over a field. THANK YOU for this!!
