Yawf is simple tool for creating WBFS files from Wii ISO images. It is just a front-end for the Wiimms ISO Tools (Wit) and features Gnome desktop integration and a focus on usability.

A parsing problem with the output of wbfs_file was fixed. The locations are remembered in choosers dialogs. A check for enough free disk space was added. The information shown about disc sizes was simplified. For example, trim size wasn't useful because an ISO to WBFS conversion always implies scrubbing the disc image. Translations were updated.
