Several features have been added, but the program should still be considered as a demo. However several areas are now functional:
* It's possible to load examples/demos
* Describtions follow the examples (Select 'More Info' from the file menu.)
* The XML storage system is now functional.
* So far a 2D version, but W is able to draw several interesting Minkowski diagrams from the example files.
* Transformations between frames is working, and new frames can be added from the menus.
Soon more will be added:
* Calculation of four-vectors.
* Many more examples.
* Most of the menus will be active.
It's still my hope, that later a '3D' version will be released. So far, I have problems with the 3D-plotting, so this has been postponed.
