I have just uploaded a new build of Library Creator XML 2.0 alpha to the forums. In this latest build I have added back most of the functions that are available in the 1.0 version. Only the Rwy12 export is still missing, I will try to add that again in the next build.
But I have also added some completely new functionality. You can now drag and drop your MDL files onto the tool from Windows Explorer. This makes it even easier to add objects to your object library.
So check out this latest version and as soon as I have added all functionality back, I will also start to write a good manual.
