Overview

Reads a \n separated list of filenames from /var/lib/YaST2/filenames Lines starting with "#" are ignored (comments) A line starting with "" is taken as the default filename, the "" is stripped

All files are listed in an editable combo box, where the user can easily switch between files and even add a new file

At finish, the list of filenames is written back to /var/lib/YaST2/filenames adapting the default line (starting with "*") accordingly.

The default is either given as WFM::Args(0) or is the file last viewed.
