When that is finished the next version gets released!
Planed for the future is another feature:
Connecting the application to a emulationdatabase. It will display the creatures and gameobjects from the database and allows you to spawn and modify new ones. So its pretty easy to combine editing client and database very smooth. So this tool will get usefull even if you dont plan to modify the client to get a faster and easier way of spawning/modifying npcs and gameobjects!
