From the NIG-homepage:
NIG in its current form has come to an end. It needs to be re-designed. So, JIG was born. It'll be a long time before anything is ready for a release though. At the moment, baby-JIG reads CSV files very fast, not much else. Any ideas about the directions to take are welcome. These are the things planned so far:
Anything that gets old fairly quickly will be loaded from external configuration files (signature recognition, combinations)
Support for different languages is a possibility
HTML files should be completely customizable
Better Google Earth support (KMZ)
JFreeChart library could be used for creating some pretty cool graphics
Selecting notes => statistics for the year 2008, all notes from a certain country, etc.
Hope JIG is growing well.
