First of all, this is amazing, a really good job.
Now, as an idea/question, do you plan to do some type of system to automátically publish/download 3dn settings? Would be really nice to load a game and be able to choose the settings from a real repository.
If you don't plan to do it and don't mind I can do it as an external program and even host the database for this.
Keep the good job!
