I'm currently working on the appearance editor but it is a fairly significant feature and it will take some time to develop. So the next version may not be out for a bit.
I'll add this, if not in the next release, then the one after that.
I downloaded this editor because I wanted to force the completionf of Gobling Trouble quest, I let the workers kill Lawrence before returing the goblin head to him. It is a bug, the game should either cancel this quest or let you complete it somehow. Anyway, I understand this can't be done with this editor? There was no readme and I could not find anything related with quests when I loaded my latest savegame in the editor. Any help?
Quest editing isn't supported yet. Not sure when I will get to it, and it's not something I'm currently working on.
