Adding objects works like this:
Type the path to the object (e.g. Creature\Illidan\Illidan.m2) into the pink field. After that click into the world to get the focus out of the inputbox. Then move the mousecursor to the position where the model should be placed and hit the 'j'-Key. If you have selected a WMO or MDX you can hit 'y' to copy that model (rotation and orientation will not be taken).
Here are some more information about what is planned:
Lot of peoples would like those projects to be open source. Me too im normally release my applications open source. But the wow-section is a business where you cant do that. So the app will rest closed source. But there will be a feature that will compense that!
The plug-in-system!
The plug-in-system is an advanced interface for you to create own functionalities for the application. You can add your own UI-elements, you can draw 3D or 2D objects, there is a possibility to implement own functions of raising/lowering terrain and so on! This is handled simply using DLL-files and a specialized pluginmanager. Examples for that will follow soon!
I guess further releases will come saturday cause i need to reset my computer
