Each list is stored in an XML document. The DTD for the XML document is
distributed with the source. The application remembers the last used
file and reloads it on startup, if it exists. It also maintains a list
of most recently loaded files to make it easier to manage a number of
lists. The preferencs are stored in $HOME/.kitlist-2 on Linux
based systems, and $HOME/Library/Preferences/kitlist-2
Preferences on macOS. It is a text file, so it’s entries can be
modified with a text editor. Perhaps a future version of Kitlist will
provide a preferences page to modify these.
