The INI file reader, readStitchItINI, reads both the user's INI file and the default INI file that comes with StitchIt. If you wish to add a new variable then all existing INI files out in the wild won't have this variable. To get around this problem, all you have to do is define your new variable in the default INI file stitchitConf_DEFAULT.ini and set it to a sensible value. e.g. If you new variable is used to enable/disable adding a smiley face on top of each stitched section, then obviously set this behavior to be disabled since most people won't want this. You can then add this variable to your own personal INI file and enable it.
